Thanks for replying to a question about such an old product.
I tried manually removing most references to Roxio in the registry. I was able to get the Install program to ask for the license key, which it had not been doing, but when the install was finished there was not trace of Creator NXT in the Start menu or on the desktop. So I basically made things worse. I have restored the deleted registry entries and restored Roxio program files from my backup drive. I have most of the system working so I think I will leave it alone and maybe look at different solutions for why the Video editor is not working. I am attaching a new screenshot. I suspect that the install failed because I forgot to turn off Norton Anti-Virus. I tried to upload the install log but this system won't let me upload a .log file.
