Hi, I just received a Nero Ultimate CD disk ordered from ebay, with serial #. It's version 18.104.22.168. The PC is as shown on the subject header, desktop, 500 MB real RAM, P3 500 MHz. I have been unable to install the product so far, & reading some user reviews, maybe I should not. I have not found system requirements for this product. Will it even install on such a slow PC, and if so, will it work? I read that this forum has good install instructions for nero. If it's a good idea to try installing, where might I find the instructions here? Thanks.
