Windows 10 here, but also not able to start the game. A few weeks ago it started without any problems.

Game starts and works on my Windows 11

Win 11 has a problem with many "old" games. So does video card drivers. This game is over 15 years old. Devs are long gone, so there won't be any patches.

Have you tried running the game as Administrator? That works for some people.

Same here. Game simply won't start at all.
I set "Run as Administrator", but nothing.
Windows 11.

Same problem.

If I go to the local folder's location and try to run the executable, I get the 0xc0000007b error.

Googled the problem and tried anything I came across, nothing works.

I finished the game twice before on older computers so I'm rather confused why this one doesn't work.

Same here. Windows 10. Game will not start..................


EDIT : Re-installed, the game still still not start.

Whatever the problem was, the game starts now.

Do you know what fixed it?

I've tried on multiple machines for months, still no go. I click "play" and then it shows that it's starting up, and then it just dies and the "play" button is available again.

That seems to have worked for a lot of people. Not me though. Still nothing.

I do recommend people who had problem to try this the last thread I saw this seems to have fixed the problem for a lot of people so, I guess good odds.

Thanks for this information. I have had the game in my library for quite a while, and decided to try it tonight, and I had the exact same problem with it not starting. I went to the PCGamingWiki and used the solution with reducing the number of CPU cores and sure enough, it worked for me.

Hopefully this fix will work for you guys!

1. Download Process Lasso:
- Download and install the free software called Process Lasso. This software will allow you to set your CPU Affinity.

2. Open Process Lasso:
- Ensure that Steam is running.
- Open Process Lasso and go to the 'Active Processes' tab.

3. Find and Configure 'steam.exe':
- Locate 'steam.exe' in the list of active processes. Note that it may disappear and reappear; just wait if necessary.
- Right-click on 'steam.exe', navigate to CPU Affinity -> Current -> Select CPU Affinity.

4. Set CPU Affinity:
- Check only CPU 0-4 (a total of five check-boxes), then click 'OK'.

5. Launch the Game:
- Try launching your game. If it doesn't work, experiment further with the CPU Affinity settings.

Note: You will need to repeat this process every time you start Steam and wish to play the game.

I was not able to start it either. I sent a ticket on their official site. Unfortunately they list the game as a "legacy game"
