Norton Security Backup problems incl. error 8507, 125
I could use some help understanding and resolving this issue with Norton Security Backup...
I’m running what I understand to be the latest version: 188.8.131.52
In Windows 10 Home from a non-Admin account:-
The Backup main summary screen always shows: Never Run, Last Backup: Not Available, Backup Sets: 0
When I hit ‘Run Backup’ it fails immediately with “Error Found Norton Security has encountered an error 8507, 125”
Then autofix checks for a fix and is unable to find an automated fix.
In Windows 10 Home from an Admin account:-
I can create and edit new backup sets, but the changes are reset after trying to run backup i.e. changes to backup sets are lost.
I can run a full backup, but not subsequent incremental backups.
The Backup main summary screen always shows: Never Run, Last Backup: Not Available, Backup Sets: 0 (occasionally shows 1 after a full backup).
The only references I can find to error '8507, 125' suggest that there’s a conflict with another security software (tho’ I don't know that these documented errors pertained to backup problems).
The only other security software I was running was IBM Trusteer/Rapport which had run alongside Norton for years okay but which I thus uninstalled and then ran Norton Security uninstall/reinstall – made no difference to this Backup issue. I have now done uninstall/reinstall of Norton three times.
The only recent significant change to my PC’s Windows 10 landscape has been in the installation and use of BT Cloud for offsite backup of photos. I wasn’t logged in to BT Cloud when running Norton Backup, but I uninstalled BT Cloud as a test and its absence made no difference to the Norton Backup problem even after another reinstall.
