says: "Lucas Simpsons Hit & Run Launcher.exe will be compressed only after closing the application using it. Modifications will be lost if you close WinRAR before that "

Based on my tests, that's what WinRAR says if a file, opened from within an archive, is deleted (from the temporary location WinRAR extracts it to, to run it), so it sounds like, in both cases, the executable is getting deleted. The executable unexpectedly getting deleted sounds to me like a false-positive in your antivirus software, causing it to delete it.

According to VirusTotal, none of the antivirus software, it supports, currently considers version 1.24 of the Mod Launcher a virus:

What antivirus software do you use?

the mod launcher disappears

Do you mean the Mod Launcher executable file (Lucas Simpsons Hit & Run Mod Launcher.exe) is deleted or its window closes?

And can you please confirm the exact version you were having the issue with? Was it 1.24 (currently the newest version) or another version?

Yours sincerely,
Lucas Cardellini

The two crash dumps you submitted seem to be for crashes caused by not having an audio output device (such as speakers or headphones) connected. The Simpsons: Hit & Run requires at least one audio output device to run.

You can prevent the Mod Launcher from bypassing compatibility mode by unticking Ignore Compatibility Layers on the Game page of the Launcher Settings window (accessible from the Open... button at the bottom left of the Mod Launcher window). This will require the Launcher to be run as administrator (as compatibility mode for Windows 98 / Windows Me causes the game to be run as administrator and the Launcher won't be able to access it otherwise).

If the Launcher isn't saving crash dumps, you can open Windows Reliability Monitor (which you should be able to find by searching for "reliability" and choosing View reliability history), find the crash there, double click it (or right click it and choose View technical details) and either take a screenshot of that and either post it here or save it as a file and submit it to that same Dropbox File Request or click Copy to clipboard (at the bottom left) and either paste that here or save it in a text file and submit it to the Dropbox File Request.

As of version 1.21 of Lucas' Simpsons Hit & Run Mod Launcher, all hacks are a single Hacks.dll file within the DLLs folder.

The Free Roam hack from SHAR MP is also included with the Mod Launcher (it should be listed on the Settings page if you have Pages enabled) since version 1.21 so there's no need to copy it.

Yours sincerely,

I was able to replicate this issue as well. It was a separate incompatibility with Windows XP which should now also be fixed in another update I just pushed: multiplayer.donutteam.com/download.html

Sorry for the inconvenience.

Yours sincerely,
Lucas Cardellini

@MrDonoB

Yes; if you have Donut Mod ticked and you click Open... at the bottom left of the Mod Launcher main window and then click Saved Games in the menu that appears, it should open the folder containing Donut Mod's saved game files.

Yours sincerely,

@thundergivesmeglee, if it crashes after giving you the option to save, isn't there text in the log on the program window (visible both before attempting to save, while the save window is still open, and after attempting to save while the crash window is still open)? And even if there isn't any information about the crash displayed, I might be able to tell something from the type of crash message and what the program window looked like at the point it crashed.

I don't really think the original issue is caused by a difference in your game given the number of people who have had the issue; however, I am concerned that my program is crashing for you.

Yours sincerely,
Lucas Cardellini

@thundergivesmeglee, can I please have a screenshot of the crash? Can you please also include the program window and, if possible, the log in the screenshot?

EDIT: What version of Windows are you using?

Yours sincerely,
Lucas Cardellini

@thundergivesmeglee, does it give you any details about the crash?

Do you have a DLL file in the same folder as it called "LucasStuff.dll" and/or "LucasStuff.Radical.dll"? Those DLL files are not supposed to be distributed as they are embedded in any tools that need them and them being in the same folder as a tool will cause it to load the version in the folder rather than the embedded version which can cause issues if the one in the folder isn't the correct version for the tool.

Yours sincerely,

@thundergivesmeglee, can you please download Lucas' Simpsons Hit & Run Install Verifier, if "Lucas Simpsons Hit & Run Mod Launcher.exe", its "Hacks" folder or its "Mods" folder are in your game directory, move them elsewhere, open "Lucas' Simpsons Hit & Run Install Verifier.exe", click Start, wait for it to complete, save the file it prompts to save and if the save isn't more than a few tens of megabytes, send it to me with this Dropbox file request (it does not require a Dropbox account) otherwise if it is more than a few tens of megabytes, just give me the contents of the log displayed on the window after it completes using a site like Pastebin.com?

I doubt the issue is a problem with your game install, especally since @gibstack693 had the same issue with two different installs, but this will tell me everything about your game directory and its contents which should help to replicate the issue, especially if you have a version of the game I haven't seen before.

Yours sincerely,
Lucas Cardellini

Okay, thank you, @thundergivesmeglee. I wouldn't expect 60-70 frames a second to cause any issues with the game, especially with file loading. On computers with two or more processor cores, running Windows Vista or newer, the game takes a really long time to load files. This can be worked around by forcing the game to run on a single processor core which is one of the things compatibility mode for Windows 95/98 does. My launcher includes a hack that is always enabled called Modern Computer Support that fixes this issue.

@thundergivesmeglee, did it crash for you when starting the mission or partway through?

Yours sincerely,
Lucas Cardellini

@thundergivesmeglee, what sort of frame rate do you usually get when not using Frame Limiter? What do you mean by "map chunks"? Do you mean entire region files (things like this)? What exactly do you mean by "fail to load properly"? Not load at all? Take a long time to load? Or have some sort of other issue once loaded?

At what point did it crash for you, @thundergivesmeglee? Does it crash every time you try it?

Does using Frame Limiter with Limit While On Loading Screens ticked in its settings mitigate the crash? You should also try that, @gibstack693.

Yours sincerely,
Lucas Cardellini

The new version of Donut Mod requires version 1.11 of Lucas' Simpsons Hit & Run Mod Launcher. Do you still have a copy of the old version of Donut Mod you can try with version 1.10.1 of Lucas' Simpsons Hit & Run Mod Launcher?

Yours sincerely,
Lucas Cardellini

Thank you. I don't see any problems from that log either but just to be safe, can you please move Lucas Simpsons Hit & Run Mod Launcher.exe, its Hacks folder and its Mods folder out of your game directory to somewhere else on your computer (to prevent them from being included in the output) and run Lucas' Simpsons Hit & Run Install Verifier again and send me the output file from it? You can send me the file directly using this Dropbox file requset (it does not require a Dropbox account) or you can use another service like MEGA if you prefer.

By default, the file should be named the name of your computer followed by "Lucas Simpsons Hit & Run Differences.lsp.gz" however Windows may not show the ".gz" if you have Hide extensions for known file types enabled which is the default. You may be able to open gzip files depending on what programs you have installed on your computer but the LSP file inside it is my own format and no publically available program will be able to open it. You don't need to open it, it just contains the log and other information about your game directory including copies of any contained files it finds and doesn't recognise (shown in the log with an asterisk).

Can you please try version 1.10.1 of Lucas' Simpsons Hit & Run Mod Launcher (assuming that you have the issue with a version of Donut Mod that supports it)?

Lucas' Simpsons Hit & Run Mod Launcher does not need to be in your game directory; however, it shouldn't cause any problems if it is, but can you please try it from another location just in case?

Was Donut Mod the only mod in the mods list enabled when having the issue? If not, what other mods did you have enabled and can you please try it with no other mods enabled. You can use the Enabled category to make sure all enabled mods are listed (even any you've hidden).

Yours sincerely,
Lucas Cardellini
