I can never install these hotfixes. If I install it with the 10.12's installed it says drivers allready up to date. If I unistall 10.12 then try these it cant find a supported card. Is there some trick? I have a Gigabyte 6850 and Vista Ultimate x64. It would be nice if someone can help.
I have MSI R6870 Twin Frozr II Radeon HD 6870 1GB 256-bit GDDR5 same.. uninstall 10.12 and 3Dmark 11 and Unigine Heaven 2.1 say I have an Unsupported DirectX 11 card/ No DirectX 11 compatible Hardware Found.
DXDiag indicates I have DirectX 11, GPU-Z 5.0 says I have 8.801 (Cat 10.12) Driver when I Restart/ Boot Up my computer but until I run- reinstall cat 10.12 both above benchmarks will not run.
my OS: Vista Ultimate 64 bit SP2.
1) Windows/Control Panel/Programs and Features ..Uninstall CCC.
2) Delete all AMD and ATI Folders in Programs Folder.
3) Delete items inside Prefetch Folder.
4) Goto Device Manager , Display , Video Card and Uninstall Driver.
5) Download if you don't have it Driver Sweeper, check the ATI Display box and run it.
6) Restart computer. Windows Standard VGA driver should install.
7) Install whatever driver then Hot Fix.
DL Driver independently ( as Stand Alone) and Install Display Driver. Don't use whole Catalyst package or trying to Check Driver box in Catalyst.
