This is the full error message (and sorry I just saw that you put it on pastebin in the first post).

This file isn't ours, so there's nothing we can do. You could try running some of the builtin troubleshooters, or perhaps the "sfc /scannow" command (in an elevated prompt) might help. It's possible that you have an aggressive antivirus or admin policy that you may be able to disable. Otherwise, for a corrupt install database, I'd guess you're looking at a Windows reset/reinstall.

If you have any success, please let us know what worked. If it turns out to be something within our control, we can try and make a change, but I suspect it'll just be handy to know for next time someone hits an issue like this.
