From ATIs InstallManagerApp.RPT:
Exception code: C0000005 ACCESS_VIOLATION
Fault address: 735A54EE 01:000844EE C:\Windows\WinSxS\amd64_microsoft.vc80.mfc_1fc8b3b9a1e18e3b_8.0.50727.1833_none_8442d417329336b1\MFC80U.DLL
After many hours of searching i found out that i should avoid mfc dlls version 8.0.50727.1833 (that was most likely installed by sql server 2008).
Adobe had same problem with their installer and found a solution:
Fix: Installing the attached vcredist_x86.exe will install a new version (8.0.50727.3079) of the Microsoft redistributable DLLs including mfc80u.dll to resolve this issue http://www.adobe.com/support/products/e ... erver.html
...but it is only for x86 applications and i needed x64. I tried to find vcredist_x64.exe version 8.0.50727.3079 but had no luck with that (downloaded 4 different redistributable packages), it seems that ms is still testing that version and it is not available to everyone. Then i searched some more on internet and found a way to change dll bindings from older to newer versions and also deleted MFC80U.DLL v8.0.50727.1833, after that installer is not crashing anymore (hooray!) but i still cant install driver properly.
From device manager: "Windows has stopped this device because it has reported problems. (Code 43)". And i'm so tired (and angry) from all this that i dont know what more i could try...
I restarted my pc like 1000000 times, tried all kind of stuff including removing and changing moemory sticks. Also tried Driver Cleaner and there is no difference.
It seems that it would have been more easier to just install windows from scratch
