To enable the use of your NAG software you will need a relevant licence key. Instructions for obtaining a licence key are included in the products Installer's Note. Alternatively you can complete the ‘Request a Licence Key’ web form here. If you've already been supplied with a licence key from our Support Desk then you will not need to complete this form/request a key. In the event of difficulty please contact your NAG Technical Support Service.
