I used to have a problem where when I started the autorun for certain games it used to start my ATI drivers installer instead!! And the problem wasnt limited to just one type of installer either.
The games did however install correctly if I just skipped the autorun and installed straight from the Setup.exe.
The problem turned out to be with my ATI card. I completely uninstalled the drivers, removed any entries from the registry and reinstalled.
Everything fixed.
Just something worth considering and its why I asked if you had an ATI card Bob.
