just install over the top - if it's not active, it won't do any harm.
Ok, I installed the install set over the top. The laptop encrypted with no errors and I'm able to reboot to PBA and log on. Now, when I try to decrypt, I receive that same error when I try to authenticate (e0020007). Authenticate from SBFS and from database give me the same error. Is there another way to remove EE or fix that error?
