Windows 7: Run-time error 50003: Unexpected Error

Hi folks,

Windows 7 64-bit Professional.

This error popped up only about a week ago. I'm getting this error when trying to run a previous version of hijackthis, or install a newer version of hijackthis. I have attempted to do this with and without UAC enabled.

I also noticed that around the same time, my ATI Catalyst Control center started having issues on startup.

I did not have Windows Update enabled at the time that this started happening, and therefore do not think it was a bad update.

I do not have any reason to believe I have a virus or infection. I don't have any Google redirects, and everything looks pretty much clean as far as further investigation.


From what I understand, this error has something to do with the comdlg32 and comctl32 OCX/DLL files in SysWOW64. I've already replaced the ocx files with different versions of the VB6 runtimes. I've registered them with regsvr32, and it says complete, but I still get the error every single time.

I've scoured the internet, and cannot find a feasible solution. Any ideas?

Thanks,
JB
