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.
