Windows 7: "Setup was unable to determine...BitLocker"

28 Oct 2009   #1

Vista Home Premium 64-bit SP2
"Setup was unable to determine...BitLocker"

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.

Well, I know the Vista Home Premium version does not contain Bit Locker, are you encrypting the drives any other way?

Just asking, but are you compressing the drive?

Thanks for the reply. No, I'm not compressing the least I don't think so. I am running Intel Matrix Storage Manager and the 2 drives are set up as RAID 1, mirroring. Could this be what's confusing Windows 7?
