Greetings,

We have an academic license for PrinceXML which we use with a self-hosted install of Pressbooks.

We upgraded to the latest version of Prince, and now receive "inapplicable license for this version."

We are running RHEL7 Linux. Pressbooks is at 3.9.5

Do we need to purchase the academic upgrade license? Thanks.

Yes, you will need to purchase a support contract to upgrade your license for Prince 11.

Just purchased support contract today. Thanks.
