I also found the installation to be non-functional. After installing the SoS download package and rebooting as required (ugh!), I opened the Nero ControlCenter and entered the key, which was accepted as a key for Nero MediaHome 2019 Standard. Then I opened Nero Start, and everything on the panel requires a separate download. I downloaded and installed Nero MediaHome from there, and it won’t accept the key. It says it’s a valid key, but not for MediaHome.
