Download Sonar, start the program, and click on "help" in the toolbar. In the dropdown, you'll see "offline activation". Click it, then click "export authorization request", and it will put a request file on your desktop. Put that file on a USB stick, and take it to an online computer. Go to your account section on Cakewalk's site. Click on "activate". It will say "choose file". Double click the request file from your USB stick and hit "submit. Cakewalk will put an authorization file in the download folder. Save that to your USB stick and take it to your offline computer. Open Sonar, click "help", then "offline activation", then "import authorization file". Select the file you received from Cakewalk, and import it, and you're done. Hope that helps.
