Hello guys/gals.. Please forgive the noob question, but I did a couple of searches (nero upgrade and nero essentials) and didn't find a direct answer to my question. OS = Windows Vista. I recently purchased a Sony DVD-/+RW (DRU-120C) drive and it came with Nero Essentials 7. The serial number is buried somewhere in the installation process, but I'm unable to find it in the registry (at this point I've uninstalled the included Nero and run the Nero Cleaner). When I reinstall it I do not see the serial number show up, although I do remember seeing it the 1st time I installed it. Can I upgrade from this essentials version(7) to 126.96.36.199 if I can find the serial number? If not and I download 188.8.131.52 is it time limited or limited in some other form? Also, and help finding the serial number would be greatly appreciated, although I think I can find that with some more digging. Thanks in advance... I've already learned a good bit from browsing the forums.
