Recently I bought a VGA card, "ATI Radeon HD4650", and after that I installed it on my PC, I can't run any .exe files just from my CD-Rom! Even when I attempted to install the driver of the 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 a DVD (more than 5 different games I have tried). It prompted me with:
setup.exe is not a valid win32 application so I couldn't install the game, in addition I need to say that there's nothing wrong with the DVD's and my DVD-Rom.
What should I do?
