Command Conquer Generals Zero Hour: Are you defeated from the start of the game?

Do you experience that all your buildings explode and blow up from 20-30 seconds from the beginning of the game?

Then the solution might be putting the game on Windows 2000 Compatability Mode instead of XP SP3 that fixed my problem.

The way you do this is:
1. To click the right mouse button on the icon of the game and choose 'Properties' in the menu.

2. Then click on the tap 'Equipment Compatibility'

3. From here you click the little square under 'Equipment Compatibility Mode'
4. Then you click the Scroo-Down Menu and choose to run the game in 'Windows 2000'


And then the problom should be solved :D
