This article describes what to do when encountering the error "Invalid Key".
Resolution:
Ensure that when entering the key Application Server Licenses are those that use AppTrack. If you get the above error you are most likely trying to enter the key in the wrong license database. A developer license should be entered in the Licence Manager database. By default this is similar to /usr/bin/mflmf or /opt/lib/mflmf.
