Hi all, thanks for providing a place where users can help users, thats great. I own a ful retail version of nero 18.104.22.168 that we had installed on our computer when we bought it(at first i thought it was an OEM but a nero tech. guy identified it as full retail)and have been thoroughly enjoying the purchace. Recently i bought a second PC and was wondering if i am able to use the retail version that i own already on this new one. Now i figure that this should be no problem and that this is actually a really silly question but i want to check with those that might know before i accidentally invalidate my serial. If this would work on my new computer, would i just be able to unlock a trial version with the serial #(that i bought and paid for)? Most of the discs that came with my older system when we bought it are buried in boxes in the back room, and to be quite honest im not even sure dell sent one which the nero page said should have been the case (i think im going to ave to call up dell about that one) I had sent an email to nero tech support, who have usually been very responsive, but have yet to recieve a reply on this. I am very greatfull for a community such as this, i use tech support forums for a lot of things and was sort of bummed that the official nero page didnt take advantage of the benefits of one.
