This set up will automate the process (NeroPatent.exe deletion, ProductRegistration.dll deletion).
A lot of people installed Nero 8, then found that there's no keygen that works good, will ask you to buy the product after 15 days, but this one here will eliminate the Nero Patent.exe so will not ask you again to buy the product as it thinks that you have purchased it!
So if you have Nero 8 installed on your machine and started to give you the 'Non-Licenced' message, all you have to do is run this app and Nero starts to work permanently.
