Some of our products, like Vinyl, don't allow iLok authorization. Please authorize with your serial number on your computer.
If your product does allow iLok authorization and you still receive this error, please open iLok License Manager and find your license under the "available" tab. You can drag it to your iLok USB icon from here. If you don't have a physical iLok USB, iLok authorization will not work.
For additional iLok authorization troubleshooting, you can head to the iLok authorization article.
