I recently convinced my parents to let me update the computer to Windows 7 from windows XP... So I had to re install Catalyst.... When I installed it I noticed it was installing stuff I didn't want (Microsoft visual basic 2007 or something like that) so I cancelled the install... and re installed it without that stuff.... but I cant open any Catalyst programs... so I tried to uninstall it... but it says I need to repair it... but when I repair it, it says I can't repair it... so I just tried running the installer again... but it doesn't help...
