I own PS elements 7.0, recently I went to download it onto my new device, and when asked for the serial number, it said that it was invalid. However it was the code given to me under my adobe products tab.
So my question is, is there anyway I can download it and activate it onto my new device or am I SOL?
There has been a change in the licensing/security function for Elements. I don't know if this will help with such an old version, but try downloading the free Creative Cloud application and then activate the program again. There is no need to subscribe to any of the Creative Cloud applications. Just install and forget it.
