When I try to enter my license key, it says "Invalid Authorization key". I have a key for "Spotlight on Oracle Xpert".
Incompatibility between Spotlight on Oracle (Standard edition) and Spotlight on Oracle (Xpert edition) keys.
Please make sure you are entering the key in the right place. Launch Spotlight, go to Help | About Spotlight, click on the Spotlight Modules tab, and scroll down to Spotlight on Oracle Xpert, and click on the button to edit the license. Then exit and restart Spotlight for the change to take effect.
