when you run the InCDxxxUP.exe file downloaded from Ahead's website, it determines if you're entitled to have InCD (that is if you have a working copy of Nero installed). if you already have InCD installed it updates it, if not but you have Nero it installs it anew, a full version of InCD not a demo.
One Ring to rule them all, One Ring to find them,
One Ring to bring them all and in the darkness bind them
In the land of Mordor, where the Shadows lie
