Did you run the installer to install QU or did you copy/restore it from a backup?  In any case, try running the QU installer again.  The installer takes care of permissions in that folder.  If you get the same message, manually delete that redo.ses file (if one exists) using File Explorer.  This sort of thing can happen when restoring files: file permissions/ownership get messed up.

Other than that, the only other thing that can cause a similar problem is Norton AV: Norton has a disturbing new trend where they try to deny access to the ProgramData folder.  Guess they think the ProgramData folder is for something other than... well... program data!

I believe this issue is related to the fact that Qimage installer does not permit non-administrators to run the program. Try running as an administrator account and these types of errors don't appear. This is a criticism I have with the installer and way the program is designed to run. Don't go blaming AV programs for a problem with your installation!

"Spraying" this same message in every new thread does not make it true: you can easily install as a non-admin and run it as a non-admin.  Refer to my answer in the other 3 threads where you made the same complaint.
