According to two Adobe customer support reps I spoke with, one must obtain an unlocking code every time you reinstall the product in order to "relicense" it. Maybe this only deals with the trial version but I got the impression this was the case even if you purchased Photoshop Elements on a CD. I may, of course, have misunderstood.Gail,
I purchased Photoshop Elements a week ago and had to re-install the
product and did not have to re-register. I have not read anything
in their doc that indicated that I needed to re-register the
product. Unless you are talking about having to enter the serial
number each time you install???
