So recently I've installed Windows 8.1 through Bootcamp on an iMac (late 2014). I've ran the bootcamp setup and the following has been showing:
Device Manager lists an NVIDIA GeForce GTX 660M, rather than the AMD Radeon R9 M295X
I've tried running the AMD setup in the startup disk made by both Bootcamp and downloaded from AMD's own bootcamp driver software, yet both seem to give the following error:
Application install: install package failure!
I've tried manually changing the drivers of the graphics card through the device manager, but that fails as well. Can anyone give me an idea on how to fix this?
