Just to let everybody know that even if you have purchased Norton ghost 15 is a fully fledged product that it will not activate on Windows 8.1. I had a chat session on the Symantec website and all they would say is that they couldn't help and just go to community.norton.com! They might as well recommended I search on Google!
As is typical of Symantec, they have a similar product under a different name but of course will charge again
