I bought PageMaker 6.5 in when I was teaching, and I have been retired over ten years. I upgraded to InDesign 3 in 2007. Two weeks ago my hard drive crashed. In installing InDesign 3 again, I'm asked for old PM6.5 serial number, which I can't find. I've used PageMaker since it was put out by Aldus in the 80s, and I have the first serial number from that set of floppies, from which I upgraded to all others, but I'm told no serial # from PM 6.5, I have to buy it all again!!!!! Is there any reason in this?
It looks like you have got an upgrade version of the new product. this means that you must have an old product that you used to obtain a discount on Adobe product. Therefore, the Installation process needs to verify this and the only way to do this is to have your old serial number. I wish I had your valid e-mail address to advise you further.
