Upgrade from Vista to Win7


Any advice on how I can solve the following issue when I try to upgrade to Win7?

The following issues are preventing Windows from upgrading. Cancel the upgrade, complete each task, and then restart the upgrade to continue.

  • [*]Setup was unable to determine if BitLocker Drive Encryption is in use.
Thanks a lot in advance,
Do you have any USB Thumbdrives attached to the system when you start the upgrade process? If so remove them and see if it helps solve the issue.
Have you tried to disable BitLocker? Do you have BitLocker on for any part of your internal drives?
