ok when you write "Windows 8, Vista & WinXP: Use your computer's uninstall-a-program option (in control panel). Do an express uninstall of the AMD Catalyst Install Manager"
I don't know what to do. What should i uninstall ? the driver with amd catalyst install manager? I cannot only delete the amd install manager itself. it's impossible. I must uninstall the driver or the amd vision engine control center for example.
