      Hello WojtekD

      We will have to check license details of the customer to understand this better, please can you share the customer email address and customer number to ansys-discovery-support@ansys.com?

      Hello WojtekD

      I can see that their Ansys Discovery Ultimate license is not active on any device yet, please try activating the license via command lines options shown below: 

      Discovery Subscription license - Command line options - Knowledge Base - Ansys Discovery Forum

      Also, there tecs has expired on: 2021-03-23, so they should only be able to use versions released before this date. 

      Let me know if further assistance is needed.

      Thank you.

        Please can you ask them to try launching Discovery using Admin rights and see if that helps?

        If the problem persists, type %temp% in Windows Search and locate .ansys folder. Zip this folder and send it to Discovery Support Team

        Also, send following log files located at ~/Ansys Inc



        Install.err (if it exists)
