I've installed the latest Catalyst and other Software on my Windows 7 64-Bit System. Everything was ok but since the last boot all my 32-Bit Application won't work anymore. I figured out that the 32-Bit apps loads the 64-bit DLLs (Dependency Walker helped me here). Using Google I found another person who had that same problem:

Fixing the "path" variable didn't helped me here. I can't (re)install the Microsoft Visual C++ 2005/2008/2010 x86 bcs. they are 32-Bit apps. ;-)

How can I solve my riddle?

Use Windows System Restore pick a date before you installed the Catalyst software. – Moab Apr 12 '11 at 19:25

I have the same problem and I discovered the problem went away for me when uninstalling the ATI Catalyst 11.3 software and driver. Alternatively you could try a system restore from a restore point from before you installed ATI Catalyst 11.3. The next problem however is that the 11.4 preview driver also has the same behavior after installing and I'm afraid if I will be able to update ATI Catalyst in the future.

Is there any chance you installed the Windows 7 Service Pack 1 update? I had the same issue and was unable to resolve it. I ended up wiping the system clean and reinstalling fresh in a fit of geek rage.

Nope, SP1 is not yet installed. The problem began in the moment where I installed the latest ATI Catalyst 11.3 incl. the AMD SDK. Deinstalling did not solve the problem. :| – Michael Freitner Apr 12 '11 at 19:28
Installing SP1 is a good idea and might fix my problem. I will try that first. – Michael Freitner Apr 12 '11 at 19:42
It got worse. Now the system won't boot anymore (Error C0190003 during update). :| – Michael Freitner Apr 12 '11 at 20:14
You could give System Restore a shot. Careful you don't too much after the SP1 upgrade as most configurations only keep the 4 or 5 most recent "restore points". You want to be sure you have a pre-SP1 restore point to get back to. – Aaron Lampros Apr 12 '11 at 20:20
