Hello John,
Can you please change the Discovery License Mode Manager to Subscription Mode then try activating the license? Discovery License Mode manager can be found under the Ansys Folder.
If that does not help, please try activating via command lines options mentioned in this article Discovery Subscription license - Command line options - Ansys Knowledge
Let me know if you still face any problems.
Regards,
Devendra
