Cannot reinstall Animate 3 (Educational) after Upgrading to Mac OS Sierra

Ater upgrading to Mac OS 10.12, I can no longer open Toon Boom Animate 3 (see attached image). Please tell me that there exists a patch in order to get it working again, as I do not have the budget to upgrade to Harmony at the moment.

I have the same issue, did you find a solution?

Did you return the license before the O.S. update?
