How can I transfer my license to my new machine I am building? Old machine will be cleaned and given to charity.
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.
I have a slight problem. I don't know where the license exists on the machine and when I try the "retrieve" option it asks for an email.
Go to My Account - Directory Opus and login with your old email address and licence code. You can then update your email address, and retrieve your certificate.
