Photoshop elements is what I purchased 7/23/14. I opened an account, signed in, followed directions to adobe.com/go/getserial. Put in my numbers on the card in my Cd box, it gave me a serial number. I carefully wrote down that series of numbers. I double checked, my daughter rechecked that I had copied correctly. Went back to entry, user name, country, then serial number. Sorry does not support this serial number". I have tried 1/2 the night. I am at a loss. Adobe customer care just doesn't.
