I am trying to install Nero Premium 7 on Vista and I cannot even get past the serial number stage. I purchased it online from Nero and downloaded the installer from the link provided. When I run it all goes well until the point where you need to enter the serial number. I enter the serial number received in the confirmation email from Nero and select "Next". A few seconds later I get a popup stating that the serial number entered is invalid. The only solution is to abort the install. I have even tried installing the trial version and get the same error message with the default (demo) serial number. If I try and run the install on another PC running Vista it all works OK. Any ideas what would be preventing the installer from rejecting any entered serial number? Does anyone else have the same problem? I am still waiting for a response from Nero support.
