A purchased version. Why?
You should install Adobe applications rather than transferring them.
Thanks. I purchased a Mac Mini and used a Super Duper Snow Leopard backup from my Macbook Pro to migrate to Moumtain Lion on the Mini.
Photoshop worked for a couple of months until I backed up using Time Machine. No Optical drive on Mini. Guess I better get one.
