I have a Radeon 7540 here and try to install the proper driver for Windows 7.
I should note that I tried a manual install (directly via the hardware manager) of the latest released version 13.1 as well as the latest beta 13.2 and both showed the same result.
I tries to install it but after a while it aborts saying that it found a driver but encountered some error and shows this particular message
"The driver selected for this device does not support this version of Windows."
I saw that quite a few people had this issue but with no apparent solution. Would anyone here know more?
