Re: I changed to a new computer, but after I installed the software, went to set up, entered the serial number, then a pop up window tells me: "the serial # you enter is valid but a qualifying product was not found on your computer" and on the selection

I downloaded it again but after typing my serial # it keeps asking me to try for another qualifying product. My old product  from which I upgraded is Cs5 extended, which is not shown the list.
