We had the same issue after an update in early 2020. Fixed by uninstalling, clean-up delete, reinstall as ADMIN.
- Follow WD’s directions for uninstalling WD Backup (Uninstall in Windows)
- Delete the following WD Backup Index Files from the C drive:
-
c:\ProgramData\WesternDigital\
- This will contain c:\ProgramData\WesternDigital\WDBackup
and c:\ProgramData\WesternDigital\Logs\WDBackup\
- This will contain c:\ProgramData\WesternDigital\WDBackup
-
Also delete - c:\Users[Customer User Account]\AppData\Roaming\Western Digital\WD Backup\
- Delete ANY desktop icons or other old WD Backup shortcuts
- Do a cold reboot. (Shutdown/Power up)
- Install as Administrator
