How are you trying to Restore? The Help file says double click the icon and they will be restored to the original location. If you have moved the file to your desktop PC from the laptop and tried this it will likely fail as it can`t find the original location.
You can Restore to any location by using the features in the Restore Wizard - the Help file should give you all you need to do this. Logically both Nero and the file need to be on the PC to do it.
