My Windows 7 machine has begun failing with the message
Windows Backup failed while determining libraries location of one of
the users included in backup.
Details: Bitlocker Drive Encryption cannot be used because
critical BitLocker system files are missing or corrupted.
I have tried various fixes from Microsoft and repeatedly tried my system repair disk without success. I did find that when I chose to select the folders to back up, the error occurred ony when I included the Pictures folder within the Libraries. I looked to see if any of the picture files were located in a location that did not exist or was not accessible but could find nothing out of the ordinary. Since Windows 7 HP doesn't even use BitLocker I can't understand why this even crops up. Any help would be much appreciated.
