The result what you got is right. In windows vista Norton GoBack will not work. Its not Compatible with vista.
"Norton GoBack" is just a software which took the screen shots for the entire OS. So in case if anything goes wrong we could use that. In vista that particular feature is inbuit. So you dont have to worry about that.
The only norton version which is compatible with vista is norton2007. So go ahead and enjoy the newer version of windows.
