Help! Uninstalled game but can't reinstall

I can't reinstall the game. I uninstalled it because it crashed alot. Then I put the CD back in to reinstall it but the popup doesnt come up letting me install it. I tried to run autorun or rungame.exe from the CD but it acts like it's gonna go into the game, but then crashes.

Help appreciated.

Damn, I'm stupid. I was using disc 2 instead of disc 1.
