Everytime i try to install a game to my computer like "The Sims," the same screen appears. The screen says; Welcome to microsft windows xp what do you want to do? -> install xp -> Perform addition tasks -> check system compatibility so i install the game by going to the cd and go to the setup file and launch the setup! That did work, but when i add new expansion packs to my game The Sims, which requires updating the installation, it brings me right back to the page where it says; Welcome to microsft windows xp what do you want to do? -> install xp -> Perform addition tasks -> check system compatibility why is this? Please help!
