From Common purchasing, upgrading and licensing questions
I've got a new computer, how do I move my licence over?
There's nothing special you need to do. Simply uninstall Opus from your old machine (make sure you backup your configuration first using the Settings / Backup & Restore command) and then reinstall on your new machine using your existing licence certificate. If you've lost your certificate you can have it resent using the self-service support page on the GPSoftware website.
