Norton Security Suite Version 5.1.0.29

I recently upgraded to NSS from Norton 360 (version 4 I think...). I have never been able to get Registry Cleanup to run in any versions of Norton 360. I get the same error message every time: "Unable to take required System Restore point, error: 126". I recieved support from Norton on the older versions, but nothing worked and I gave up on that tool. Everything else works fine, just curious if anyone else has had this issue and if there has been any way to fix it.

 

Thanks in advance!
