recently I've bought a VGA card, "ATI Radeon HD4650", and after that I installed it on my PC, i cant run any .exe files just from my CD-Rom ! even when i attempt to install the driver of VGA Card, I couldn't do that, So I downloaded it and installed it with no problems. after that when I try to install some games from DVD (more than 5 different games I have tried) it prompt me with: "setup.exe is not a valid win32 application"
therefore I cant install the game, in addition I need to say that there's nothing wrong with DVD's and my DVD-Rom.
I would really appreciate if you just can help me through this one !
