Can anybody had problems running CoD World at War on Vista? When I run the game, it closes and reports me that the application stopped running. On Windows 7, it works.
Im running it on Vista with no probs.
Maybe try to patch it to 1.2
I think that is the last of the performance patches.
The rest concern online issues.
I could be wrong.
Also check your performance logs, maybe they will shed some light on what went wrong.
