Hi all,
Thank you for sharing the issue and I am very sorry about the experience!
If you are using a previous Archicad versions, I believe the license in your machine needs to be upgraded in order to recognize and run with Archicad 24. As it was mentioned by Barry and Ralph in this thread:
https://archicad-talk.graphisoft.com/viewtopic.php?p=313287#p313287, upgrading license to 24 is not yet available in Australia. Please contact your local support for a correct information on when the upgrade is available.
Thank you for your understanding (and enthusiasm with the new release)! Let me know if there are any further questions!
Have a great day!
Best regards,
Minh
