Most of my Adobe products have stopped working - CS4. I'm getting the "Licensing for this product has stopped working" error with code 15. One of the last solutions suggested by Adobe is to do a full uninstall and I want to deactivate the license. How do I do that if the software isn't even opening properly?
You just uninstall. Any lost activations thereafter must be gathered by caling phone support and have them reset the counter on the server.
To add to Mylenium's postt if you have problems aafter you uninstall you can run the cleanup script which you can get from adobe which removes the licensing file.
However there might be another solution, why not do a Google search for licensing stop working for Adobe Illustrator CS 4 ( or just CS4 apps)and see if you locate some kind of tech note about how to fix.
I maybe falsely remembering something but the think there is a fix for this.
