To use your Nero software after installation, you must activate it with your serial number.
A serial number cannot be used on more than one computer, it only is valid for one PC.
If you have already installed and activated your Nero product on one PC, but now want to use it on another computer, please proceed as follows:
1. remove the serial number from the Nero Control Center on the old computer (see screenshot). Please note that you won't be able to use Nero on your old computer anymore.
2. activate your Nero product on your new computer with the same serial number.
