If you do not know yet, the keys above will give you a licensed Nero 7 Ultra Edition. I have already tried both keys and both works. The first time, I downloaded a copy of Nero from its own official website. That should be nero 188.8.131.52 at that time and i used the first set of keys. After a while, i changed OS and so i have to install another one. I downloaded the most recent installer, nero premium reloaded 184.108.40.206. Luckily, the keys still work and this time i used the second set. I believe, both keys will work with any installer as long as they are version 7s.
