Thanks for your response. I will turn off my registry cleaner and try that. But, I run this program on another computer, same OS, same registry cleaner and it doesn't affect that one. As far as the time between attempts, I should clarify. When I do a repair or reinstall, it works fine. It's when I shut my computer down and restart it. Then Roxio doesn't recognize. And finally, I can use the burner with other programs after Roxio stops recognizing.
