TRON 2.0: Killer App Mod Help And Troubleshooting Guide

By TronFAQ on Saturday, November 20, 2010 at 7:56 AM
I've been seeing a lot of people doing Google searches, trying to find help when they have problems with the Killer App Mod. (You would think they'd read the ModDB site page or the documentation that comes with the mod, that already has troubleshooting advice in it. Or try to contact the creators when they have difficulties. But I guess people are impatient.)

Anyway, rather than have troubleshooting advice scattered through various sites, I'm going to collect all the advice together into one concise article.

This article is a work in progress, and will be edited from time to time to update and/or improve the information contained within it.

LAST UPDATED April 18th, 2020

Q: When I use the mod, widescreen doesn't work. How can I fix this?

A: First, before installing the mod, make sure you are correctly identifying the aspect ratio and resolution your monitor is capable of.

Popular aspect ratios and resolutions:
  • 4:3 (640x480, 800x600, 1024x768, 1280x960, 1600x1200)
  • 5:4 (1280x1024)
  • 16:9 (1280x720 aka 720p, 1360x768, 1920x1080 aka 1080p)
  • 16:10 (1200x800, 1440x900, 1680x1050, 1920x1200, 2560x1600)
Once you've determined your aspect ratio and desktop resolution, select them during the installation of the mod when it asks for this information.

After the mod has been installed and you run the game: if from the TRON 2.0 main menu you go to Options > Display, the game will reset the resolution back down to 640x480. You will not be able to select any resolution that isn't in 4:3 aspect ratio, because the game does not allow you to choose them. (This is something that will be remedied in the upcoming v1.2 of the Killer App Mod.)

If this happens, quit the game and run the TRON 2.0 game launcher, then click the Display button. You will be able to select your non-4:3 widescreen resolution there, starting with v1.1a of the mod.

If the game is still not correctly displaying in widescreen, you might need to alter your GPU Scaling settings in the Nvidia Forceware or AMD/ATI Catalyst control panel.

Here are links to guides on how to change your GPU Scaling settings:

Turning on Nvidia GPU scaling (change setting to Aspect ratio)
Turning on AMD/ATI GPU scaling (change setting to Maintain aspect ratio)

In both cases, the selection you need to choose may be blanked out. To fix this, temporarily lower your desktop resolution at least one setting below your current one. Then when you go back to the control panel, the option should be selectable. After making the change, return to your original desktop resolution. The setting might not appear to stick, but it should still be working. This is a flaw in both Nvidia's and AMD/ATI's drivers.

It's also possible that your monitor has an aspect ratio setting. This feature is sometimes called 1:1 pixel mapping. If your video card is set to use GPU scaling, this monitor feature should be turned off. Or, if your video card isn't using GPU scaling, then you will probably want to turn this feature on. But don't have both on at the same time.

If none of the above has helped, be aware that recent Nvidia drivers have had problems with correctly displaying games without "black bars" even when the Aspect ratio setting is used. Read this message topic to learn more details.

Q: After installing the game, when I run it: it either crashes or I can hear music but I'm getting a blank or black screen. What can I do to fix this?

A: Locate your TRON 2.0 folder in the Windows Explorer and go inside it. If you installed the CD/DVD version of the game to the default location, it will be at:

C:\Program Files\Buena Vista Interactive\Tron 2.0
(Windows XP/Vista/7/8 32-bit)


C:\Program Files (x86)\Buena Vista Interactive\Tron 2.0
(Vista/7/8 64-bit)

If you installed the Steam version of the game to the default location, it will be at:

C:\Program Files\Steam\SteamApps\common\Tron 2.0
(Windows XP/Vista/7/8 32-bit)


C:\Program Files (x86)\Steam\SteamApps\common\Tron 2.0
(Vista/7/8 64-bit)

In your TRON 2.0 folder, highlight Lithtech.exe, and click the right mouse button. Click Properties, choose the Compatibility tab, put a checkmark in the box beside Disable desktop composition (Windows Vista and 7 only), and/or set Compatibility mode to Windows XP SP2 or 98. A few people have reported that this helps.

Another thing to try, is hitting the Esc key a few times. Sometimes the game will get "stuck" when displaying the introductory videos and hitting Esc will skip them. This might take you to the main menu. If you click the Options button in the TRON 2.0 game launcher, there is a setting called Disable Movies that allows you to turn off the introductory videos.

Before installing the Killer App Mod, you should install the Unofficial v1.042 Patch rather than the Official one. The Official Patch still uses copy protection that does a disc check, which doesn't work so well for some people on newer versions of Windows like Vista/7/8. Note that the Killer App Mod adds Français/Deutsch/Italiano/Español language support to the Unofficial Patch.

DO NOT patch the game or use any kind of No-CD crack AFTER the Killer App Mod is installed. This will prevent the game from running at all. A No-CD crack is not necessary, because the Unofficial Patch recommended during the mod installation eliminates the disc check.

If none of the above works, visit this message topic. Download the file mentioned and run the registry script. But only do this as a last resort if the other suggestion didn't help. It forces TRON 2.0 to reset all its settings, and you will lose your preferences that you set in the game.

Q: I can't get the Killer App Mod to install at all. The installer hangs or crashes during installation. What can I do?

A: Thanks to Moravuscz on the Steam discussion forums for suggesting this easier solution, if the installer hangs. It's strongly suggested to try this first, before trying anything else listed further below. This easier solution works on Windows 7/8/10.

  • Run the Killer App Mod installer (if you cancelled installation earlier), and wait until it hangs again
  • Hit the Windows key and R simultaneously
  • A window named Run will appear, type resmon and hit Enter
  • If a Windows User Account Control (UAC) prompt appears, click Yes
  • Click the CPU tab in the Resource Monitor window
  • Scroll through the list of processes until you find the irsetup.exe entry (which should be highlighted in red), and place the mouse pointer on top of it
  • Right-click and choose Analyze Wait Chain
  • A window will appear, showing which process irsetup.exe is waiting on and causing it to hang (the process irsetup.exe is waiting on will be different for everyone)
  • Click the small box next to the process irsetup.exe is waiting on (to put a checkmark in it), then click the End process button
  • A dialog will appear asking to confirm if you want to end the conflicting process, so click the second End process button
  • Close the Resource Monitor window, to return to the Killer App Mod installation screen

After following the above steps, the Killer App Mod installer should now resume and complete installation.

Below are additional troubleshooting steps you can try (if you're on Windows XP/Vista for example), but the above steps should resolve the Killer App Mod installer hanging issue for the majority of people. (The hang is due to a bug in the installation software, used to create the Killer App Mod installer. The developer acknowledged, and has claimed to fix, this issue in an update to the software. This hanging problem doesn't occur for everyone. But for those who do encounter it, the issue should no longer occur in the upcoming Killer App Mod v1.2, when it's released.)

In order to determine which processes can cause this hanging issue, if everyone could please do the following I would very much appreciate it.

Download this batch file (saving it to your Desktop will make it easy to find) > Right-click it and choose Run as administrator (If the Windows 8 SmartScreen prompt appears, click More info and then Run anyway) > Wait until the Command Prompt window closes, do not close it yourself (this can take a couple of minutes) > Click here to start composing an e-mail (address is tronfaq@ldso.net) > Add the msinfo32.nfo file that should now be on your C: drive (at the root, not in any folders) as an e-mail attachment > Also attach the file TRON 2.0 Killer App Mod Setup Log.txt that should be in your C:\Windows folder.

For advice on how to solve this issue:

Before trying anything else, some users have reported that quitting their Razer (Comms/Cortex/Synapse/Booster) or Logitech (Gaming/SetPoint) software, allowed the mod to install.

In the case of Razer software, you may also need to stop the Razer Game Scanner service. Please visit this page and scroll to the bottom. Instead of restarting the Game Scanner service, follow the instructions but choose to Stop the service instead and then try installing the mod. (The service will automatically start again, the next time you restart your computer.)

Next, try unplugging any USB storage devices such as Flash memory keys. This may help.

The next step to try, is simply restarting Windows and attempt installation again.

If this does not work, try setting the installer to run in XP Compatibility mode. At least one person has reported that this helped.

Right-click ka_mod_v1x1a_setup.exe > Choose Properties > Click the Compatibility tab > Put a checkmark in the box beside Run this program in compatibility mode for > Select Windows XP (Service Pack 2) from the drop-down menu > Click OK.

If that doesn't work, try installing the mod in Windows Safe Mode. On Windows XP/Vista/7, Restart the computer from the Start Menu, and before the Windows bootup logo appears, hit the F8 key on the keyboard. This will bring up a menu. Choose Safe Mode. When you reach the desktop, run the installer again. After installation of the mod completes, restart the computer once more and it will automatically return to the normal desktop.

In the case of Windows 8, the F8 key alone no longer works when booting and reaching Safe Mode is a bit more awkward.

Hit the Windows key and R simultaneously on the desktop > A window named Run will appear, type msconfig and hit Enter > Click the Boot tab > Put a checkmark in the box beside Safe boot > Click OK > Click Restart. When you reach the desktop in Safe Mode, try installing the mod again.

After installation of the mod in Safe Mode has finished: Repeat the steps to run the System Configuration (msconfig) program > Remove the checkmark in the box beside Safe boot > Click OK and Restart to return to the normal desktop.

If the installer complains that a previous version of the mod is installed, say Yes to deleting the mod folder.

Note that the installer will require approximately 2.5GB of hard drive space in order to install the mod. (1.5GB for installed files, and 1GB temporary space during installation.)

Q: During installation of the Killer App Mod, when it reaches the patching stage I get a "Not enough disk space" error. Even though I have plenty of free space. Why is this happening?

A: There is an issue with the patching software used during the installation process. If TRON 2.0 is installed on a drive partition with greater than 2TB of free space, the patching software incorrectly calculates the amount of space and this error occurs. (I've already contacted the developer of the software, and asked them to fix this.)

To get around the problem: Download this .zip file (saving it to your Desktop will make it easy to find) > Copy/extract the contents of the .zip to your desktop > Right-click freespace_v1x0.bat and choose Run as administrator (If the Windows 8 SmartScreen prompt appears, click More info and then Run anyway) > When the batch file runs and asks for a drive, type in the letter of the drive partition where TRON 2.0 is installed.

The batch file will use Contig.exe to create a temporary blank file, large enough to bring the free space on the partition down to less than 2TB. It will then pause, and allow you to attempt installing the mod again. Do not close the window. Once the mod has been successfully installed, return to the open batch file window and press any key. The temporary blank file will be deleted.

Q: When I try to install the mod, my anti-virus quarantines or deletes some or all of the Killer App Mod installer files. (This may also happen silently, without the anti-virus notifying you.) Should I be worried?

A: No, the Killer App Mod installer absolutely does not contain any kind of virus. Your anti-virus program is giving you what's known as a false positive. Some anti-viruses are overzealous and incorrectly identify the compression used on the installer, or its patching activities, as suspicious.

Here's a link to an online virus scan site, to which the Killer App Mod installer runtime was submitted for scanning. The site reported the setup program as being clean.

Setup - Virustotal result

Q: When I try to manage my subroutines in the System Memory screen (accessed by hitting the F1 key), if I place my cursor on top of a subroutine it doesn't highlight. I have to move the cursor slightly off to the side, to get it to highlight. Why is this happening?

A: This occurs when playing at 16:9 and 16:10 widescreen resolutions (more noticeable in 16:9 aspect). Although most of the changes needed for TRON 2.0 to work in widescreen resolutions were successfully implemented, this particular issue was a challenge to resolve and is true for both v1.1 and v1.1a of the Killer App Mod. However, in the upcoming v1.2 of the mod, this issue has been fixed and will no longer occur.

A tip to help make managing subroutines a bit less difficult, is to click the right mouse button on a subroutine. Rather than left click, and drag it around. Clicking the right mouse button will cause the subroutine to jump in or out of Jet's memory ring. Using the mouse scroll wheel will allow you to cycle through the subroutines in each of the three subroutine libraries, rather than having to click on the arrows, which will make finding subroutines hidden off-screen much easier.

Q: The game used to work with the mod installed, but now it keeps crashing. Why has it suddenly stopped working?

A: Unfortunately, a bug has been discovered in the Mod Manager. When it edits the game's configuration files, it sometimes removes a space or newline by mistake. Entries in the config files then get mashed together, and the game doesn't do error checking so it just crashes with Error copying file cres.dll, Could not init CircuitButeMgr, Couldn't initialize DebrisMgr, or a Client MFC error.

If you see the messages Error copying file cres.dll, Could not init CircuitButeMgr, or Couldn't initialize DebrisMgr, then just use the TRON 2.0 game launcher to run the game instead. This should solve the problem.

If you get a Client MFC error, look for the following files in the Windows Explorer if you installed the CD/DVD version of the game to the default location:

C:\Program Files\Buena Vista Interactive\Tron 2.0\Profiles\ProfileName.txt
C:\Program Files\Buena Vista Interactive\Tron 2.0\Profiles\_ProfileName.txt

(Windows XP/Vista/7/8 32-bit)


C:\Program Files (x86)\Buena Vista Interactive\Tron 2.0\Profiles\ProfileName.txt
C:\Program Files (x86)\Buena Vista Interactive\Tron 2.0\Profiles\_ProfileName.txt

(Vista/7/8 64-bit)

Look for the following files if you installed the Steam version of the game to the default location:

C:\Program Files\Steam\SteamApps\common\Tron 2.0\Profiles\ProfileName.txt
C:\Program Files\Steam\SteamApps\common\Tron 2.0\Profiles\_ProfileName.txt

(Windows XP/Vista/7/8 32-bit)


C:\Program Files (x86)\Steam\SteamApps\common\Tron 2.0\Profiles\ProfileName.txt
C:\Program Files (x86)\Steam\SteamApps\common\Tron 2.0\Profiles\_ProfileName.txt

(Vista/7/8 64-bit)

Where ProfileName is the name of the current player profile you are using in the game. The defaults will be Player.txt and _Player.txt.

Load both files into a text editor, and look for the following entries in both the ProfileName.txt and _ProfileName.txt files:

PlayerModel = xxPlayerName = "PlayerName"

Change them to this, and save the changes in both files:

PlayerModel = xx
PlayerName = "PlayerName"

By separating the entries on to different lines, the game will no longer crash. The xx represents a number you will see in the files, and PlayerName represents the player name that you have chosen for yourself.

This issue with the Mod Manager will be fixed in the upcoming v1.2 of the Killer App Mod.

Q: In the Single Player Light Cycle section of the game, I can't access all of the Light Cycle colors. The original colors are locked, and it seems as though the new colors added by the mod are locked as well. How can I access them?

A: By default, the mod locks the original Light Cycle colors and provides new Light Cycle colors that are unlocked.

If all the colors are actually locked, then something has gone wrong. Try running the Killer App Mod manager and make sure that the program shows New Light Cycles Unlocked. If not, place an X in the box beside it.

If you change your Player Profile name after the mod is installed, it will cause the Light Cycles to become locked again and you will get the error message The player profile PlayerName.txt could not be found. Where PlayerName is the name of your current profile. If you want to change your profile name, do it before installing the mod. If you change your profile back to the default Player, the error message will stop appearing and the Light Cycles will be unlocked again.

Note that this does not affect Multiplayer. All Light Cycle colors, both original and new, are always available there.

Q: I'm getting all sorts of graphical glitches, such as transparent or missing items (like the Light Cycle floor grid) or corrupted geometry. Is the mod causing this?

A: No.

On AMD/ATI cards, an anti-aliasing setting can cause geometry to become transparent when it shouldn't be, or even disappear altogether. While with Nvidia cards, recent Forceware drivers are not always working well with TRON 2.0. The graphic anomalies on Nvidia cards are confirmed both by myself, and independently verified by Stevedroid in this topic, to happen whether or not the Killer App Mod is installed and active.

If you own an AMD/ATI card
Change the Anti-Aliasing type from Adaptive to one of the others in the Catalyst control panel. This will cure transparent or missing geometry.

If you own an Nvidia card
There is currently nothing you can do to prevent the graphic anomalies except hit Alt-Tab to leave the game and then hit Alt-Tab again to come back. This resets the game's renderer and should clear up the glitches.

Changing the Power management mode (under Manage 3D settings) in the Nvidia control panel to Prefer maximum performance, seems to help a little to improve loading times and slightly decrease the occurrence of glitches.

Also, be sure that your graphics card is not overheating. Download and install a utility like MSI Afterburner to check your video card's temperature. On average, a video card should not go above 80° degrees Celsius, though some cards can go as high as 100° degrees while continuing to operate normally. Check around to see what temperature is normal for your video card while operating under full load playing games.

Q: I'm getting some other strange glitches. For example, on the Primary Docking Port level, an E-mail Archive Bin or I/O Node is far above or below where I can reach it. Or in the later fCon themed levels, particularly Command Module, the game sometimes crashes. Is the mod causing this?

A: Once again, the answer is no. These also happen without the mod, and are game bugs that were not fixed in the last v1.042 patch for TRON 2.0.

The problem with an E-mail Archive Bin or I/O Node being too high or low occurs quite rarely. If it does, loading the Autosave for the current level or an earlier save from the previous level, and playing through the game again until you reach the same point should eliminate it.

As for the crashing on later fCon themed levels, it seems to happen most often when fighting DataWraiths. There is really nothing you can do about it, except save often and reload after the game crashes, so you can try to get past the crashes and finish the game.

Q: Sometimes when a level loads the game freezes/hangs, and I have to end the process Lithtech.exe from the Task Manager to exit the game. Is the mod causing this?

A: Again, no. This is a bug that has existed in the game, from before the mod was even released. Sometimes when loading a saved game multiple times in rapid succession, the game will hang. There is not much that can be done about this.

Q: When I quit the game, it crashes sometimes. Is the mod causing this?

A: No. This happens without the mod, on vanilla TRON 2.0, as well. The game crashing on exit does no harm, but is quite annoying. To prevent the game from crashing on exit, try adding it to the Data Execution Prevention (DEP) exception list. This should solve the issue.

Go into the Windows Control Panel > Click System > Click Advanced System Settings on the left side of the window > Click the Advanced tab on the window that pops up > Click the Settings button under Performance > Click the Data Execution Prevention tab > Click the radio button labelled Turn on DEP for all programs and services except those I select > Click the Add button near the bottom.

If you installed the CD/DVD version of the game to the default location, browse to:

C:\Program Files\Buena Vista Interactive\Tron 2.0
(Windows XP/Vista/7/8 32-bit)


C:\Program Files (x86)\Buena Vista Interactive\Tron 2.0
(Vista/7/8 64-bit)

If you installed the Steam version of the game to the default location, browse to:

C:\Program Files\Steam\SteamApps\common\Tron 2.0
(Windows XP/Vista/7/8 32-bit)


C:\Program Files (x86)\Steam\SteamApps\common\Tron 2.0
(Vista/7/8 64-bit)

Select Lithtech.exe and click Open > Make sure you see an entry labelled Client MFC Application, with a checkmark in a box beside it > Click OK > Restart the computer.

Q: When the animation of Jet appears on the main menu, he looks very strange and is partially black. Why is this?

A: From the game's main menu, go into Options > Performance > Display. If the Dynamic lights setting is turned off, then turn it on. This will alleviate the issue.

Q: I'm stuck on the third level (Program Integration). I used the Gold cheat, and Byte is now asking me to optimize a subroutine. I can't continue without optimizing, but it seems that all the subroutines are gold. What do I do now?

A: Even if you used the Gold cheat, one subroutine was deliberately left in Beta form. Precisely to prevent you from getting stuck at this point. Look for the Prankster Bit subroutine in the top subroutine library. This subroutine can be optimized and will allow you to continue.

Q: With the mod installed and active, I'm not able to connect to any servers in Multiplayer. Why is that happening?

A: Everyone must be using Version 1.1a of the mod in order to play together online. Even the server hosting the game must have the mod enabled.

LDSO does run Killer App Mod servers, but only on weekends. Every Friday evening to Sunday evening.

If there are no servers running the mod at the time you want to play: you will need to contact server operators and request that they put servers with the mod online, or host your own server.

    I don't know where you got your version of the game from. Perhaps it's a pirated version or some kind of "remix" that I've been seeing. Which is probably using a customized installer.

    But the original retail version of Tron 2.0 will install in a 64-bit version of Windows, and the game will run on all 64-bit versions of Windows.

    Mod run fine, but I can't pick up energy. Health is fine. Energy things make the noise like I am using it but the value never goes up and the energy balls never deplete.
  4. TronFAQ January 22, 2011 10:18 PM
    The blue patch routines are Infinite Energy and never deplete. Only the green and red ones do.

    As for your energy bar not increasing, there's a bug in the game where sometimes the bar won't show an increase even though you have increased your energy level. Going to the System Memory screen with the subroutines and then leaving it again, will usually correct this.

    Hello. I had a lot of fun playing through the game again with improved graphics from the Killer App 2 Mod. I have a question about the second mod: User Error 2. I am running a dual core P2.4Ghz processor with 4 gigs of ram and Windows Vista. It has an nVidia GEForce 9600M graphics card. I have had NO GLITCHES OR ERRORS with Killer App or Tron 2.0. My problem is with the installation of Rez Handler. After I install and run it, it specifically says "Component 'COMDLG32.OCX' or one of its dependencies not correctly registered: a file is missing or invalid"

    Well, I didnt change the install directory of rezhandler or the game installation. I had no previous problems with Killer APP installs or graphics or anything!

    Is there something I can do or a guide/FAQ pointer I have missed??
  6. Anonymous May 29, 2011 7:33 PM
    Ok. thx for the mod, but heres the problem: I downloaded everything, enabled admin mode, I did all the stuff you said, then I downloaded killer app mod, and when it was at the very end, the setup crashed. I tried again, and it said that I already have it installed. I tried everything: from reinstalling tron 2.0 to searching the directory. can you help me?
  7. TronFAQ May 30, 2011 9:54 PM
    @NintendoManX (or anyone else who has that problem with REZ Handler):



    Like it says above:

    "If the installer complains that a previous version of the mod is installed, you'll need to delete a folder on your hard drive. If TRON 2.0 was installed to the default location, it will be at:

    C:\Program Files\Buena Vista Interactive\Tron 2.0\Custom\Mods\Retail
    (Windows XP, Vista or 7 32-bit)


    C:\Program Files (x86)\Buena Vista Interactive\Tron 2.0\Custom\Mods\Retail
    (Vista or 7 64-bit)

    Delete the Retail folder. The installer should now allow you to continue."

    The folder has to be there, because the installer checks for it and refuses to install if it sees the folder.

    The next version of the mod installer will be updated to handle errors more intelligently, like allowing you to install anyway and offering to delete the existing mod folder.

    I appreciate your hard work but this is madening. I've uninstalled and reinstalled everything about 5 times and it still doesn't seem to work with 1920x1080 and 16:9. I install the original game, then the unofficial 1.024 patch, then the Killer App mod. Can't figure out what could be going wrong. I look in the display.cfg and it always say 1024x768. When I load the game there are black bars on the left and right sides of the screen.
  9. Anonymous October 28, 2012 11:54 AM
    BTW, I also tried to use the mod manager to reestablish the 1080p with 16:9 and I uinstalled and reinstalled Killer App Mod to try to reset the resolution. I absolutely cannot get this to work.
  10. Anonymous October 28, 2012 12:31 PM
    Ok, I figured out that it messes up the Killer App settings even if you enter the display settings in the Tron 2.0 splash screen menu. It only works if you set it and leave everything related to the display alone.

    So I finally got into the game in 1920x1080 and it's amazing! Beautiful graphics! If only someone would figure out how to put some aggressive anti-aliasing in there.

    Anyway, thanks for this mod! I just hope future versions are more user friendly.
  11. TronFAQ October 29, 2012 8:48 PM
    @Anon on October 28th:

    I know you probably won't end up seeing this, but I'm also replying for the benefit of anyone else out there who's reading.

    The issue with not being able to go to the Display screen without the resolution resetting, is mentioned both in the readme (included with the mod) and here.

    Being able to select any resolution in the game itself isn't something that was easy to fix, so at the time v1.1 was released (over 2 years ago now) it couldn't be implemented.

    However, in v1.2 this issue has been remedied. You can see previews of upcoming changes in v1.2 of the Killer App Mod on the LDSO Youtube channel. The changes are also mentioned in news posts on ModDB.


    As for anti-aliasing, aside from using the AMD or Nvidia control panel to change your global settings (not ideal, to be sure), you can use programs like Radeon Pro and Nvidia Inspector to apply individual anti-aliasing profiles to games. Both programs can be obtained by clicking the "All TRON 2.0 Files" link on the right side of any page here, and scrolling down until you see the download links.

    I uploaded a video to the LDSO Youtube account showing Tron 2.0 at 1080p with a high anti-aliasing setting applied, and it looks great that way. Just make sure, if you have an AMD/ATI card, not to use the Adaptive anti-aliasing setting. Or else you will have geometry disappearing in the game.
  12. Unknown December 04, 2012 8:32 AM
    The problem that I am having is that the aspect ratio and resolution that I selected in the installation of the mod (1920x1080, 16:9) did not seem to stick. I have followed the directions to the letter and have not gone into the options in-game at all. If I change the display.cfg to 1920x1080, then the mod changes it back to 1024x768. I know that it is supposed to replace whatever is changed with whatever was chosen during the installion, but I did not choose 1024x768.

    I remember managing to get this working properly maybe last year when I played through it, but I cannot remember what I did to get it to use the proper resolution.

    I will keep reinstalling and trying something else but in the meantime, do you know any reason why the installer would not use the resolution that I specified? Thanks.
  13. Unknown December 04, 2012 12:01 PM
    I got it to work properly by trying one thing different: I ran Tron 2.0 in admin mode before applying the unofficial patch, then did everything else as the directions say. If anyone else has the problem that I had, this should clear it up. Thanks for your work on this mod. It allows me to continue to enjoy this game.

    Um when I try to change something in the killer app mod manager and I play the game from the manager it comes up with the error "error copying file cshell.dll" can anybody help?
  15. TronFAQ October 09, 2013 4:09 PM
    @Anon: Just run the game's own launcher instead of the Mod Manager, and the error should go away. That error, and the solution for it, are mentioned in this article.

    For those who have a blackscreen with game running (you can hear the sound).

    If you have dual monitor, disable one, it did the trick for me.

    Hope this can help.

    After copying all files to the Tron 2.0 Steam app folder, the patching process does not start. The setup process does not respond anymore and has to be ended via task manager. I'm using "ka_mod_v1x1a_sfx" with Tron 2.0 Steam on Windows 8.1

    Tried installing on Alienware laptop with Win 10 Pro following YouTube video instructions. I installed game from original CD's on D drive instead of default. I installed the Unofficial patch, started the game, closed the game then tried to install the Killer App. I keep getting a message to install the Unofficial patch. I checked the game and it shows the correct patch version.
  23. TronFAQ January 12, 2017 6:42 PM
    @Anon Jan. 12, 2017: Delete the GameDLL.rez file in your Tron 2.0 folder. Then the mod installation will work. (The Unofficial Patch was supposed to have done this for you. Don't know why it didn't. This is the first time I've ever heard of this happening.)

    Also check that there are files named Gamep5.rez and Gamep6.rez in the folder. Otherwise, the patch definitely did not install correctly.
  24. Anonymous January 12, 2017 8:30 PM
    My D drive was set to read only. I cleared the setting. Uninstalled...reinstalled according to instructions and still have the problem. The file you mention is not deleting. I see the other two files and both have the same date/time stamp from 2003. I tried deleting the GameDLL.rez file but it made no difference. I should point out that file was not capitalized as you have it in your post. I'm open to working with you to explore this issue to nail it down if necessary.

    @TronFAQ Jan. 12, 2017: I fixed my issue with the Killer App not installing. I have a brand new laptop and did not realize it arrived with the D drive set to read only. So the initial install had all the directories locked. I had to completely uninstall everything and reboot the computer to make sure the drive was cleared. After that, the installation was without any issues.
  26. TronFAQ January 13, 2017 10:42 PM
    @Anon: As soon as I read that the folder was set to read-only, it struck me as something rather odd going on. I was going to suggest that perhaps it might be another task locking the folder, for some reason. But I see you've followed up with another comment already, and solved it. That's good to hear! Glad you got it working. :)

    I am getting a "Error copying cshell.dll" message. What do I do?
  30. TronFAQ January 23, 2019 12:27 AM
    @Anon Here are some common solutions for an "Error copying cshell.dll" message.

    1) Temporarily disable your anti-malware/anti-virus program, if you have one. It could be interfering with the game.

    2) Try launching the game using the TRON.exe launcher, not the Killer App Mod Manager (if you have the mod installed).

    3) One of the game's config files may be corrupted. Specifically, autoexec.cfg or the player profile (named Player.txt by default).

    Either download the default autoexec.cfg file from here and overwrite your existing autoexec.cfg in your Tron 2.0 folder: https://steamcommunity.com/app/327740/discussions/0/2549465882930456437/#c1620599004468455993

    Or scroll up this page to the guide, and search for the answer to "The game used to work with the mod installed, but now it keeps crashing. Why has it suddenly stopped working?". You might need to edit the player profile (default name is Player.txt, but could be different) in a text editor.

    Hi, I was trying this mod with higher resolutions, but the HUD looks really small. I have been tryng to read FAQs or investigate but I could not find anything. Can the HUID be resized when using custom resolutions?
  32. TronFAQ September 28, 2019 9:23 PM
    @Armandorev The current version of the mod does scale some of the UI elements for higher resolutions. But not all of them, true. There isn't any simple way (like via editing config files) to scale the UI, unfortunately. It's something that's being worked on for the next version of the Killer App Mod, though.

    I recently re-downloaded Tron 2.0 and installed both the 1.042c patch and Tron 2.0 Killer App 1.1. Game launches fine, and I can reassign mouse controls, but cannot reassign keyboard controls. Checked to see if the autoexec.cfg file was perhaps set to Read Only, but it is not. Undid any Compatibility Mode settings on ALL executables within the Tron 2.0 folder in Steam and no joy. Reset them back, still have issue. Moved install from D: to C:, still cannot reassign keyboard commands. Also checked validity of files via Steam, and even tried WITHOUT the patches installed. Still having issue. Only way I can do so is to manually edit the autoexec.cfg file, which is a MAJOR hassle, as it uses a weird nomenclature for the keys. Plus, once figuring it out, still cannot assign the left Ctrl key to anything (want to use for melee disk attack with the use of the fire function of the disk). Again, it is unusual that I can remap mouse control and they take, but not my keyboard keys (both the laptop keyboard and my Drevo Calibur keyboard, both in Bluetooth mode and in direct connect mode via USB). I have tearing my hair out over this....any suggestions?

  35. PouffyTGM1 November 24, 2023 6:55 PM

    I got the game running on my Windows 11 laptop, and for some reason my textures are messed up on enemy deaths, with big floating "invisibles" burst out.

    Is there any way to fix this? Thanks!
  36. TronFAQ November 24, 2023 9:44 PM
    @PouffyTGM1 There are a couple of things I can think of, off the top of my head, that could be causing the kind of texture corruption you described.

    1) It can be caused by using the Alt-Tab key combination, used to leave the game and access the Windows desktop or other programs. TRON 2.0 doesn't respond well to Alt-Tab, and certain textures can become corrupt after using it. Quitting and restarting the game fixes this.

    2) This could also be related to which GPU you have. Specifically, if you're using Intel Xe graphics, which are part of Intel's Arc series of graphics cards, and the integrated graphics in their CPUs starting with the 12th Gen series (aka Alder Lake). Intel Xe dropped native support for DirectX 9, which TRON 2.0 uses. So Intel's drivers have to translate DX9 calls. While Intel continues to improve their drivers in this regard, the results are still not always good.

    Here's an article discussing how Intel Xe GPUs aren't necessarily good for playing older games, that use DirectX 9 or earlier.


    If you do have an Intel Xe GPU in your laptop, I provided some advice on how to potentially help run the game better (DXVK), here:

  37. PouffyTGM1 February 27, 2024 7:52 PM
    Sorry for the very slow response!

    I did refresh restarted and fresh installs and it didn't fix the issue.

    However, the GPU I think was the one (I do have a Intel Xe integrated graphics card). I plopped the DXVK file into the game folder, and it seems to be working fine now (bit hard to tell because I'm past the enemies that it was extremely noticeable for). Thanks for the help!
  38. ToughSun14 May 10, 2024 3:59 PM
    For some reason, after I installed this mod, every time I try to open the controls menu, the game hard crashes. Anyone know why this is, and how to fix it?
  39. TronFAQ May 13, 2024 11:52 PM
    @ToughSun14 Hmm, I've only ever heard of this happening once before, and unfortunately the person experiencing it never followed up with me.

    My best guess is one of the game's configuration files has somehow become corrupt. I suppose there's also a remote chance you recently plugged in some device via USB that the game doesn't like.

    If you're still experiencing this issue: If you could go into your Tron 2.0 folder and copy the autoexec.cfg and launchcmds.txt files, along with copying your Profiles folder, place all that into a .zip archive, and make it available for download somewhere, I could take a look at it and see if there's anything in your config files that may be causing this.
  40. ToughSun14 May 21, 2024 11:30 AM
    @TronFAQ Sure, here's a link to the MEGA repository where I uploaded the zip: https://mega.nz/file/OuAVUYgK#VDxkv42samTfXPaYiokqUZUNUUm3QaqFNDDCSuHofXU (no password required)
  41. ToughSun14 May 21, 2024 11:32 AM
    @TronFAQ Addendum: I should probably mention this for clarity sake, the game crashes when I click "configure controls" in the "controls" menu, not when I try to access the controls menu itself.
  42. TronFAQ May 23, 2024 1:15 AM
    @ToughSun14 I didn't find any corruption in your config files, but I did make a couple of observations that might be relevant to the issue.

    1) I noticed you created a new "ToughSun14" profile instead of using the default "Player", after installing the mod. If you could do me a favor and temporarily switch back to "Player" and then try clicking the "Configure Controls" option, let me know if that makes any difference.

    2) I actually suspect the previous suggestion probably won't help, because I think a more likely cause for your issue could be this: There was an entry in the autoexec.cfg file that indicated you're playing TRON 2.0 on a laptop. Does your laptop have a numerical keypad?

    Because if it doesn't, I could see why that perhaps might lead to crashing when trying to configure the controls. The game expects a numpad to be there and assigns a couple of the keyboard controls to it by default.

    I've edited your profile to not use the numpad. You'll have to rename it to match your current profile name in the Profiles folder.


    If you don't have a numpad, download the edited profile and see if it makes a difference.

    In an upcoming update to the mod, during installation there will be an option to re-assign controls to keys on the main keyboard if you have no numpad.
  43. ToughSun14 May 23, 2024 10:15 AM
    @TronFAQ Actually, my laptop's built-in keyboard DOES have a numerical keypad, yet it was still crashing. Does that help out, or is this another dead end?
  44. ToughSun14 May 23, 2024 10:20 AM
    @TronFAQ Addendum: just tried loading the new profile and opening the controls editor, still crashes.
  45. TronFAQ May 24, 2024 1:53 AM
    @ToughSun14 If you didn't have a numpad: the game crashing due to controls being assigned by default to keys that didn't exist, might have made sense to me. But, that's not it then.

    Other possibilities could be (in order from most to least likely):

    1) Disabling Windows XP SP2 compatibility mode (if it's applied anywhere) might help. The Steam version of TRON 2.0 enables this by default.

    First, if you have the Steam version, delete installScript.vdf in your Tron 2.0 folder. (It should actually already be gone, since during installation of the mod it should take care of this for you.)

    Next, right-click TRON.exe in the Tron 2.0 folder > Properties > Compatibility > remove the checkmark in the box beside "Run this program in compatibility mode" > click OK. Do all the same steps for Lithtech.exe.

    2) What are your keyboard layout and system locale settings? Since you appear to have an Nvidia 4070 GPU, that should mean you have a brand new laptop which had Windows 11 pre-installed.

    In that case, the keyboard layout can be checked by opening the Settings app > Time & language > Language & region > under "Preferred languages" the first language listed should have three dots to the right side of it > click the dots and select "Language options" > Scroll to the bottom of the window to see "Installed keyboards". Is there only one, and it's US QWERTY?

    Now to see the system locale: Click the back arrow at the top left of the Settings app window to go back to Language & region > click Administrative language settings > check what region is set under "Current language for non-Unicode programs". Is it "English (United States)"?

    I still have some more ideas, but I'll leave it there for the time being. At this point, I'm thinking the first suggestion might now be the most likely culprit.

    But, unfortunately, since I've never experienced the issue you're having during all of my testing, I haven't been able to try and troubleshoot this before now.
  46. ToughSun14 May 24, 2024 9:54 AM
    @TronFAQ Bad news: I tried both suggestions, and it STILL crashes! I gotta admit, I am really stumped right now. Well, if nothing else works, how exactly do I manually edit controls in the profile file? I want to use my gamepad with this game, but apparently I need to manually define the controls since there isn't a preset definition loaded with new profiles.
  47. ToughSun14 May 24, 2024 9:55 AM
    @TronFAQ Actually, I just thought of something. Does the game generate an error log in the event of a hard crash? If so, that could make things a lot easier to troubleshoot.
  48. TronFAQ May 25, 2024 12:31 AM
    @ToughSun14 The game doesn't generate a log file by default, but it will create one if you add these lines to the autoexec.cfg file in a text editor:

    "errorlog" "1"
    "debuglevel" "6"

    A file named error.log will then appear in your Tron 2.0 folder. The "debuglevel" controls how verbose the error log output is, and the example I gave will provide the most detail.

    Note that if you enable error log generation, it will slow down the game. So it's best to remove those lines later. Also, to be frank, I don't think the error log will provide any insight in this particular case. But, it's still worth a try I suppose.

    These are my last ideas of things to check:

    1) In the TRON 2.0 launcher, click the Options button > place an X in the box beside Disable Joysticks > click OK > click Play. See if this makes any difference.

    2) Is there any software running in the background that handles input? For keyboards, etc? For example, on an Acer laptop I have access to, they include a program named Quick Access that handles some keys on the keyboard and displays overlays on the screen when a certain key is pressed. I'm sure other laptop brands have similar software. I wonder if that would have any effect on the game.

    3) You could try disconnecting or disabling all USB/Bluetooth/Wireless devices that aren't absolutely necessary, and see what effect that has if any.

    Beyond all the suggestions I've made so far, I'm quickly running out of ideas of things to try.

    As for using a gamepad, the game's built-in support for joysticks and gamepads is poor and I don't recommend using it. You're better off using the Steam Client's Steam Input feature and creating a profile for the game that way.
  49. ToughSun14 May 25, 2024 12:44 AM
    @TronFAQ Well, here's the error log: https://mega.nz/file/irZDgajB#kzyvfPeMtLO5ETn7qhyhIVDvQ5CE0bvqkeSDdxoXyHI
    Also, tried disabling joysticks, didn't work. I don't think I have any software that would modify input. Not too sure about unplugging anything. I still want to give gamepads a chance with this game. If I can't modify the controls in-game, what do I need to modify externally to set up the controls?
  50. TronFAQ May 26, 2024 12:14 AM
    @ToughSun14 A couple more things you could try:

    1) If you have a touchpad and/or touchscreen on your laptop, try temporarily disabling them.

    2) In the TRON 2.0 launcher, temporarily disable these features: Click the Options button > place an X in the boxes beside Disable Sound, Disable Music, Disable Hardware Sound, and Disable Hardware Cursor > click OK > click Play.

    These probably aren't going to make any difference, but I just wanted to cover every esoteric thing I could think of. At this point, I'm out of ideas as to what else to try.

    If you really want to use the game's built-in gamepad support, I'll need to know what gamepad you have, and hope I have one of the same so I can try figuring out the specific values assigned when binding controls. I do have the Xbox Series X, PS5 DualSense, and Nintendo Switch Pro controllers.
  51. ToughSun14 May 26, 2024 10:33 AM
    @TronFAQ Nope. Did nothing. Still crashes. I even tried a clean install, and it still crashes there too! Although, I did try doing a quick search, and someone said that apparently, the issue is having any "USB controllers" plugged in when starting the game. But I'm not sure what that entails. I've tried not having any controllers turned on, and I even unplugged both my Xbox 360 wireless gaming receiver and my Xbox wireless adapter, still crashes. I'll admit, I'm stumped too. Also, I'm using an Xbox 360 controller, so native XInput controllers do work here. Maybe that can help you identify the bindings for external editing?
  52. TronFAQ May 27, 2024 1:11 AM
    @ToughSun14 Indeed, the game not liking a certain USB device was one of the first things I thought of and mentioned, but it seems that's not it in this case. Unfortunately, whatever is causing your issue has been really difficult to pinpoint.

    One final idea to try:

    Windows 11 Settings app > System > Display > Graphics > Look for Lithtech.exe listed as "Client" and click on it > click the Options button.

    Since you have a laptop, you might have two GPUs. The integrated one, in your CPU (which would most likely be Intel then), and the discrete Nvidia GPU.

    Check if Windows is running TRON 2.0 (Client/Lithtech) with the High performance GPU, your Nvidia 4070, just in case it isn't already.

    An Xbox 360 controller is pretty much identical to the later ones. So I could try mapping my Series X controller and see how it goes, then share the profile with the bindings for that.
  53. ToughSun14 May 27, 2024 8:27 AM
    @TronFAQ Welp. It was worth a shot, but not even that worked. I even had to manually add Lithtech.exe to the graphics settings list. Perhaps maybe at some point you could release a full list of all the bindings for anyone else who has this problem.
  54. TronFAQ May 29, 2024 12:21 AM
    @ToughSun14 So I tried using the built-in gamepad support in TRON 2.0. To preface this, I've used it in the past and knew it wouldn't be a good experience. But I hadn't tried it yet with my Series X controller which I'd recently acquired.

    Still, as expected, it did not work well. You can't adjust the deadzones for the sticks in the game. And the game doesn't recognize most of the controls. The triggers can't be used as "buttons", the d-pad duplicates one of the sticks, and some of the remaining buttons aren't recognized.

    I'll make the modified version of your profile – with the input bindings that worked – available for you to experiment with. But, again, I recommend using Steam Input instead of this.

  55. TronFAQ May 30, 2024 12:48 AM
    @ToughSun14 I don't know if you'll still see this, but one more suggestion about perhaps determining why the game is crashing on that screen.

    Run TRON 2.0 and click Configure controls to cause the game to crash again.

    Press the Windows and R keys simultaneously > in the window that appears type perfmon /rel > press Enter.

    After the Reliability Monitor window appears, look for the most recent "Client MFC" item in the list at the bottom of the window.

    Right-click it and then click "View technical details".

    The problem details might give you a clue as to why the game is crashing, if the fault is traced to something outside of the game.
  56. ToughSun14 May 30, 2024 4:09 PM
    @TronFAQ Thanks for that last suggestion. Got a crash report just like you said, here's the link: https://mega.nz/file/CjhDWAqY#J2EF2L7M96ipd8gJDEHO8LudWQvcHQ2krLy6CMunBMo
