Launching Adobe products on Mac OS X after system upgrade, migration or restore, results in error “Licensing for this product has stopped working”
Solution 1: Delete the FLEXnet Publisher folder
1. Quit all Adobe applications.
2. On your startup disk locate and delete the following folder:
/Library/Preferences/FLEXnet Publisher
3. Launch your Adobe application(s).
Note: There is also a folder named FLEXnet Publisher folder in the /Library/Application Support folder. You must not rename this one; all of your Adobe applications will stop working. Make sure you are in the /Library/Preferences folder.
This worked fine for me!
