Trying to upgrade to Windows 10 or simply want to uninstall HP Drive Encryption but can’t?
Getting the error HP Client Security Manager 8.x is required?
During a recent Windows 7 to Windows 10 upgrade I encountered this error and here is how I solved it.
First install the latest version of HP Client Security Manager
Next Install the latest version of HP Drive Encryption from here
Now uninstall HP Drive Encryption (It will let you do it this time!) and reboot again
