What version of CGMiner are you using?
What catalyst version?
What OpenCL SDK/Runtime?
Thanks,
Sam
1) 2.11.3 - March 17, 2013
2) For some reason when I search for catalyst control center, it comes up with AMD VISION Engine Control Center instead. When I click on it to open it up, nothing every opens up, so I think something might be broken there
Let me know if there is a log or file somewhere that could get you the info you need.
3) Not entirely sure how to find out about this one, however in my program files there is this: AMD APP SDK v2 (hopefully that's what you're looking for. If not let me know how and where to find out)
Sorry I could only really help with cgminer, but if you let me know where I can find this out, I'll get back to you straight away.
Cheers
