I recently got a new PC, and I have an old(er) laptop that I initially installed photoshop elements 10 via an ISO file. Since I initially installed it, I lost the box and original papers for my copy. I still have access to the ISO files. I have tried to sign in wih my current Adobe ID in my current copy of Elements 10, but it always fails. Is there a place I can find my existing Product key? It would be very nice to move Photoshop to my more powerful PC.
