I just tried to install Catalyst 6.12 drivers to the retrocompaq nr. 4, which has the Radeon 7000 32MB graphics card. The installer gave me this strange error telling me that the device isn’t working. I googled around and some people were convinced that it was a virus or malware causing the problem. So I did a quick scan but didn’t find anything.
Luckily I had another set of drivers, Catalyst 6.2, which I tried next. The installation went through without any problems and the card started to work. I guess the version 6.12 just wasn’t designed for the 7000 model?
