Best of all is a fresh install of Windows. Second to that, removing any previous AMD device drivers is a very good idea, in particular by using some sort of driver cleaner fit for the purpose. Google can help you there.
Thanks for the quick reply. This was a clean install of Windows 10 Pro. Windows automatically installed "AMD Catalyst Control Center" and "AMD software center".
With both of these installed I installed "CRT Emudriver & CRT Tools 2.0 beta 15 (Catalyst 12.6)" and that's working fine. However on every boot I was getting an "AMD software center" error. Uninstalling "AMD Radeon Settings" solved that, but I'm still left with a "AMD Catalyst Control Center" I can't use.
During my reading in the forums I discovered that since my "Radeon HD 7750" video card is also supported by the "CRT Emudriver & CRT Tools 2.0 beta 15 (Crimson 16.2.1 for GCN cards)" driver I should have used that instead. Therefore I'd like to get back to a clean slate and install the Crimson version of CRT Emudriver 2.0
My plan is to run CRT Emudriver's Setup.exe to uninstall it, but after that I'll still be left with the "AMD Catalyst Control Center". I don't see an option in "Add/remove programs" to uninstall it.
Based on the comments
here I plan on using the
AMD cleanup utility and if that doesn't work try
DDU.
