Thank you kindly for your help. I might've goofed the uninstall with Revo Pro, or perhaps I hadn't disabled Norton, so I just did a full uninstall again, and this time, I made sure I deleted everything in Moderate Mode. However, now I'm locked out from attempting another install (too many).
I just submitted a ticket with Roxio tech support to ask for more install attempts.
I do have a legit full retail boxed copy directly from Corel. Hopefully they will allow me to try again. If probs continue after re-install, I will submit another ticket to Roxio, Microsoft, or HP.
