I have been using Photoshop Elements 12 on my Computer (s). Since I bought the dvd when it first was introduced. And I have never ever had a single problem . I still have the original disc and pass key, but just recently on a New computer, Similiar to my others, it now say that I have to many computers attached to this program and requests a new serial number. I paid almost 300.00$ new for this program and I know it is old but it is very reliable and I do not want to lose it. Can you help I am on a HP 17" all in one PC.
If you still have access to your old computer(s), you can go to the Elements 12 Help menu and sign out of the program.
Otherwise, you need to contact Elements support. You can start a chat session by clicking on the blue Contact Us button under the Support menu at Adobe.com. Make it clear that all you want to do is deactivate all of your computers. You will then be able to sign in and activate Elements 12 on your new computer.
