While attempting to do an upgrade from Vista Home Premium 64 bit to Windows 7 Home Premium 64 bit I get the following message; "Setup was unable to determine if BitLocker Drive Encryption is in use." The only option then is to cancel the upgrade. I've tried installing 3 times now with the same results.
To my knowledge BitLocker isn't even installed on my pc. I have never even heard of it until this evening Should I try for a clean install? I have also had my CD/DVD drive vanish from My Computer after rebooting.
Thanks for any help.
