Hmm, as far as I know the "Windows 2000" compatibility layer just passes the OS ver to the application as Windows 2000. That's it.
 
War 3 runs fine on my Windows XP.....

the problem is it shows the intro movies and then just exits the program (like it crashes and windows terminates the task) it won't show any 3D and hardware generated scenes, not even the main menu.
if you run it in compatibility mode then it runs with no problems.

I know this is a very old topic but I have the same problem like Ali had. However, my problem is that im not excatly a computer expert so I dont know where to set the Compatibility mode. Please help me!

Straight from the mouth of Microsoft:
To set up compatibility mode (if it is not installed):
To run the Program Compatibility Wizard
 
1. Start the Program Compatibility Wizard. (Click Start, click Help and Support, click Fixing a problem, click Application and software problems, under Fix a problem click Getting older programs to run on Windows XP, and then click the Program Compatibility Wizard link in the instructions.)
 
2. Follow the instructions in the wizard.
 
Or manually
 
As an alternative to running the Program Compatibility Wizard, you can set the compatibility properties for a program manually.
 
To set the compatibility properties for a program manually
 
• Right-click the program icon on your desktop or the shortcut on the Start menu for the program you want to run, and then click Properties.
 
 
• Click the Compatibility tab, and change the compatibility settings for your program.
 
 
 
 

Yes but what settings do I use?

It really depends on the application. Some require 95/98; others W2K. Then, you have to experiment with memory settings.

I set it to Windows 2000 and it works fine. I thank you for your help.
