I'm getting the following notice in Adobe Acrobat 9 Pro:
:Error "Licensing for this product has stopped working ..."
How do I remove this?
Register it - (Never seen a problem on people who have a genuine licence key, but anyway...)
Assuming you have a legal copy
Close all Adobe programs, then Keep the directory, but delete all files in -
Next, restart any Adobe program in the same suite or just Adobe Acrobat if you purchased it on it's own (If part a suite, you have to activate other programs first).
Now register, it should activate fine. If you have a problem activating now, Contact Adobe directly. You pay so much for the products, they offer support!
Adobe published a TechNote which describes how to deal with this problem:
