These driver are base off the AMD Catalyst™ 11.11a, I just modified it so drivers and features, it should install on all versions of Windows 8 x64 & Windows Server 2008 R2 Operating Systems. The Driver, CCC2, HydraVision, Visual C++ 2010 Runtime, AVIVO, Drag N Drop Transcoding, MCE Encoder, OpenCL and WMV Decoder, had to be modified using orca to support Windows 8 x64/Server 2008 R2. Once again these are unsupported drivers and definitely not supported by AMD.
Currently don’t have a crash system to test Windows 8. Please let me know how it work out for you by stating the which version Windows 8 and video card. Hopefully the orca trick works. Thanks.
