Game doesn't launch

[Sameyes]

When I try to launch the game it says "Entry point not found" and something about engine.dll I tried to verify the game, tried all the compatibility modes, administrator, reinstalling, restarting the system, updating graphics card, changing windows resolution, some launch settings in steam and some I forgot. I checked the game files and engine.dll is there (I even tried to uninstall the engine.dll file and verified the game again so it installs it again but nothing changed). I got the game running in the task manager a few times but thats it. I can post a screenshot of the error if needed.

Edit:

So this worked for me:

You need to COPY the files in the bin folder to the game's main folder (the folder that the games exe is in).

If it works great if it doesn't:

Find mm.exe in the game's folder, right click, properties, compatibility, compatibility mode, run this program in compatibility mode for: Windows XP (Service Pack 3)

This worked for me and hopefully it does for you guys too. Dont forget you need to COPY the files don't just empty the "bin" folder.

Legend

I did what you said and copied the files from the Bin folder to the main folder and now the game is working!

Glad it helped, I figured this out I think 2 weeks ago or smth but always forgot to write it here thanks for reminding me lol.

In my case it is a problem with my new GPU not loading the game, the AMD 6750XT, but my old RX 470 runs the game just fine. I've swapped them out twice to verify. I am using the latest WHQL drivers 22.11.2.

One possible solution would be to try playing it in a virtual machine running an older version of Windows. I think XP was the latest when the game came out, but i'm guessing 7 may work too?

Hey there Paradox!

I'm sorry to hear you're having issues launching the game. Have you tried a previous version of your GPU's driver to see if this assists?

"Try this in the Startoptions under steam:

-applaunch 2100 -dxlevel 90"

I can confirm this works, at least on my semi ancient computer running Win7 ultimate. Ran the game fine yesterday, tried today, and it wouldn't run. It would start, then evaporate into the desktop with no error message at all, with the games executable running in the background doing nothing.

Now what this command line seems to do (without the end quote):
-applaunch 2100 -dxlevel 90
is, i'm guessing, reset the shader cache, or whatever cache the game has saved somewhere. Running with that command line, is like starting the game in safe mode, and I'm guessing clearing the cache. However, with that command line, modern resolutions like 1920X1080 won't be present in the options menu.

If you remove the command line arguments, the game will run like normal, after you've run it with the arguments. Again, my presumption is it's something with shader caching. What i've also noticed is that once you run the game normally, certain video options will be reset, if i remember correctly those were:
- HDR lighting
- Anti-aliasing
- Texture filtering.

Since this game is essentially half life 1, and even an old crotchety machine like mine can run it with all options MAXED without breaking a sweat, it's probably in everyones nature to crank the options. I suspect its one, or ALL of those options which are creating a cache the game has issues with at launch.

This is all just guesswork mind you.

There is a patcher that makes the game 4GB aware, and this is what got the game working for me.

There's a link to it in this steam discussion,
https://steamcommunity.com/app/2100/discussions/0/1813170373226112160/
and I think it works for other games/programs not just dmomm

Thanks for sharing your experience in this thread, I'm glad to hear that you can enjoy the game again !
