When I open Bitlocker Drive Encryption Manager in the Control Panel neither of my hard drive partitions are listed, it's just blank underneath the heading where the hard drives would be listed. The control to turn Bitlocker on or off for the drives is also not shown because it thinks there are no drives.
When I try to do a repair installation (inplace upgrade) there is an error message that shows up fairly quickly that says:
"Setup was unable to determine if BitLocker Drive Encryption is in use" and the repair installation fails.
Windows Explorer has no problem seeing the drives and I can freely open any drive, directory or file and read and write to them. How do I get Bitlocker to see the hard drive partitions?
