As i redownloaded a demo version again and it said my free trial was up .
thanks people .
You can’t. Once the free period has expired, you are supposed to either buy it or delete it. That’s how it works.
Doing what you ask would be cheating.
If you’re going to cheat, then cheat. There are many, many torrents at many sites, with cracked & pirated versions of Nero.
Nero has what they call a “clean tool”, which will remove all their products and allow a clean install.
You can then install a new version, and activate it with a purchased serial, or a serial obtained from a keygen.
Suspect
ps. I will send you a PM
