With Reason 7 and later, and Reason Essentials 2 and later, you can add your Reason, Reason Essentials and Rack Extension licenses to a single computer, for offline use.
Please note that you will need to have installed and run Reason/Reason Essentials at least once, before authorizing your computer. This is because Reason needs to install the Authorizer application, which is required for this procedure.
1. To authorize your computer, click the “Authorize” button on Your Account:
The Authorizer application starts up and the web page will list all your available authorizing options.
2. Click the “Authorize” button next to the computer icon to add all licenses to your computer:
Once you have authorized your computer you will be able to run Reason or Reason Essentials with full functionality, without Internet connection.
