Its an extra add on to Nero. If you Dont have the full version of Nero 6 Ultra then you probably dont have NVE. You can download the intire software at Nero it is free for 30 days to try. Try it out first to see if you like it. I would suggest if you do this not to load In-CD. Thats just another add on for Nero, but it gives you problems if your backing up DVD's so don't load it.
If you like Nero I suggest you get it from here
http://www.ibackups.net/index.php?main=products&sub=showproduct&id=30 It is much cheaper there than buying it from Ahead.
