    I still can’t get this to work.. Trying to downgrade from enterprise to ultimate.
    It looks ok in regedit, but after choosing upgrade, it does a compatibility check and comes back with that the versions already installed is newer than the one that i’m trying to install.
    Could that be because i have already installed servicepack 1 and the new install haven’t?
