My production licence does not work

The production licence which I obtained from the Signature SDK samples on GitHub does not work. I get an error message saying that the licence is invalid or no tablet is found.

Solution

The long-style production licence which is provided on GitHub will not work with releases of the Signature SDK prior to 3.20.4.
There are two solutions:

1. Upgrade to the latest release of the Signature SDK which is available under "For signature" at https://developer.wacom.com/en-us/developer-dashboard

2. If you are unable to upgrade please request an old-style short licence via the "Submit a request" link above.
