The Expiration Date Of Your License Has Arrived Catia -
As a CATIA user or license administrator,
I want to receive a clear, non-blocking notification that my license has expired,
So that I can save my work, understand why functionality is restricted, and take action to renew or switch licenses.
A surprisingly common cause: your computer's clock is wrong.
If you are on an academic license:
Note: Some universities provide license tokens via a VPN. Connect to your university’s VPN before launching CATIA.

If you are staring at this screen right now, here is your action plan:
1. Don't Force It Do not try to reinstall Catia. That is a multi-hour process involving registry keys and service packs. It won't fix a license expiration, and you’ll just waste time.
2. Check the Connection If you use a network license server, ping the server. Can you see it? If not, it’s a network issue, not an expiration issue. Call IT infrastructure support.
3. Locate the License File

This is what they are paid for. Send a screenshot of the error. If you have a maintenance contract, they can usually generate a new license file within minutes. You download it, drop it in the license server folder, restart the server service (usually via the LSADMIN tool), and you are back in business.
The first reaction is always denial. “No, that can’t be right. IT renewed the licenses last month.” You click 'OK' hoping the message is a glitch, a hiccup in the matrix. You try to relaunch. The message pops up again, mocking you.
Suddenly, your productivity screeches to a halt. The complex geometry living in your head has nowhere to go. You are locked out of your own creation.
