I have a pc with an ATI video card and ATI Catalyst software. I am trying to install an antivirus program and the catalyst software starts every time I click my setup file, but it is trying to install a video driver.
Delete the Catalyst, restart
install the antivirus, restart
activate, update and scan with your antivirus, turn the antivirus off.
now load the newest catalyst software, restart.
now turn the antivirus back on.
That's called a "workaround"
