I've got a Vista x64 box here that throws an error about "authz.dll is corrupt" whenever I start an application. Doesn't seem to hurt the function of the applications, but is very annoying.
So far I did:
- Malware & AV scans (nothing of note found)
- chkdsk/f (which failed to auto start on boot, had to force safe mode manually to make it run) which found no errors.
- sfc/scannow which reported back that errors were found, but it was unable to fix them. It pointed me at a log file that was many MiB of what looked like GUIDs (totally unhelpful).
If I had another Vista x64 box laying around, I'd just try and replace authz.dll with another copy, but unfortunately I do not. Googling comes up with a ton of hits that look like scammer sites and none that feel legit.
I don't know when it started as the owner didn't even know it was an issue. Reports were just that "it crashes a lot" (RAM needed reseating, was only detecting all chips about every tenth boot). So, not sure where to even start if I need a system restore. Might be so far back that it wouldn't work anyways.
Any tried and true methods for fixing this obnoxious authz.dll popup?
