I have read many complaints about installing new versions or Roxio over older versions. Normally, if I am placed in that position, I uninstall the program first. Than I go into the Win10_Pro, Program Data (Hidden Folder), Program Files x86, and then enter the registry, and manually delete all the registry files pertaining to Roxio. I don't understand why Coral has not implemented an uninstall program that would automatically delete everything referencing Creator (All Versions).
Or, I'll take the easy way out, and reformat my drive, and perform a fresh install of the O/S, and programs, etc. It may take some time, but I never experience Roxio crashing on me regardless of which ever program that I am using.
