I had so many errors while trying to install Creator that I don't remember them all. I think it mostly said the Creator Could Not Be Installed. I did delete everything Roxio using the registry, searching on Explorer, and everything I could find. When I tried to reinstall the program all I got was a screen giving me the options to modify, repair or uninstall. I tried all three to no avail.
Anyway, my screens don't look like yours. I tried reinstalling the entire program but got a message that the serial number for Aftershot was invalid, even though it is the one on the disk envelope and also on the Corel website.
