ofelas 0 Posted March 1, 2004 Hi all, The Catalyst 4.1 & 4.2 packages (as well as the seperate driver & control panel packages) will NOT install on a Sapphire 9600 Pro Atlantis under XP Pro SP1. Halfway during setup, I get an error message stating (error - islayer etc.). I can extract the 4.2 driver package & manually install the drivers via Device manager, but I also want to install the Control panel... What gives? I'd like to try the Catalyst drivers before I start experimenting with Omega drivers... Clean install of XP_SP1, and the Sapphire Pro 9600 is the only video card I have. I also have the latest inf files for the AGP etc., as well as Direct X 9.0b installed. I created a brand new additional Admin account, and tried installing from there as well...no go. Also tried after copying an NT based "islayer.dll" into my Windows/System32 directory - still no luck. I also noticed an additional error message 'could not find aticim.dll'. I finally tried Omega Driver v 2522 - still no luck.
