The Expiration Date Of Your License Has Arrived Catia -

Seeing the message "The Expiration Date Of Your License Has Arrived" in CATIA can bring high-stakes projects to a screeching halt. Whether you are an individual user or managing a fleet of workstations, this error indicates that your CAD software can no longer verify a valid, active entitlement for the product or specific workbench you are trying to use. Why Does This Error Occur?

This notification typically appears for one of three reasons:

Hard Expiration: Your annual or multi-year license term has physically ended.

System Mismatch: A hardware change (like a new network card or motherboard) has changed your "Computer ID" or "Target ID," making the old license file invalid.

Server Connection Failure: Your computer cannot "talk" to the Dassault Systèmes License Server (DSLS) due to network issues or firewall blocks. Step 1: Check Your License Status

Before assuming you need to buy a new license, verify what CATIA sees:

Launch CATIA: Even if the error pops up, the License Manager window often remains open. View Status: Look at the list of available licenses. Green: More than 30 days until expiration. Orange: Less than 30 days remaining. Red: Already expired.

Check Tools/Options: Go to Tools > Options > General > Licensing to see which configurations are currently requested. Step 2: Troubleshooting Connection Issues

If you know your license should still be valid, the issue is likely communication with the server.

Verify the Server File: CATIA looks for a file called DSLicSrv.txt located in the hidden folder C:\ProgramData\DassaultSystemes\Licenses. Ensure this file contains the correct server name and port (usually ServerName:4085).

Test Connectivity: Use the Managed DSLS Eligibility tool from Dassault Systèmes to check if your workstation can reach the license service.

Firewall Ports: Ensure ports 4084 and 4085 are open on your local machine and the server. Step 3: Resolving Hardware or "Target ID" Changes

Licenses are often "node-locked" to a specific machine's unique ID. If you have recently upgraded your PC or are using a docking station (like a Thunderbolt dock), your Target ID may have shifted. The Expiration Date Of Your License Has Arrived Catia

The notification pulsed in the center of his primary monitor, a sterile, system-red box that felt more like a gavel strike than a software alert.

THE EXPIRATION DATE OF YOUR LICENSE HAS ARRIVED.

Elias stared at the words. Behind the pop-up, the ghostly wireframe of a jet turbine assembly hung suspended in the digital void of CATIA. He had spent three months sculpting the airflow vanes, rotating the 3D model thousands of times, pulling surfaces, checking tolerances down to the micron. It was ninety-eight percent complete. It was his masterpiece.

He moved the mouse to click the "Renew" button, his muscle memory anticipating the swift redirect to the payment portal.

Connection Error. Please contact your system administrator.

He clicked again. A spinning wheel. A freeze.

Then, the dreaded cascade. The toolbars grayed out. The "Save" icon became unresponsive. The complex geometry of the turbine, once vibrant and manipulable, locked itself into a static, untouchable screenshot.

"No, no, no," Elias whispered, tapping the keyboard.

He knew the rules. He had known the date. But in the haze of overtime and the obsession with the design, the renewal had slipped from "Urgent" to "I’ll do it tomorrow."

Tomorrow had just run out.

He reached for his phone to call the IT department, but his hand stopped. It was 5:00 PM on a Friday. The IT department was a ghost town. The licensing server was likely hosted in a different time zone, managed by people who were currently sleeping. The notification pulsed in the center of his

Elias leaned back in his chair, the leather creaking in the silence of the office. He looked at the frozen screen. The software didn't care about his deadline. It didn't care about the aerodynamics or the beauty of the engineering. It was a gatekeeper, cold and absolute.

The license had expired. Access denied.

He watched as the cursor moved on its own, the system logging him out with a polite, unfeeling chime. The screen went black, leaving him with nothing but the reflection of a tired engineer staring back at a blank, useless screen.

How to Fix It (Without Losing Your Mind)

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 If you are an admin, navigate to your license server directory. You are looking for the .lic or license configuration file. Open it in a text editor. Does the EXPIRATION date read yesterday? Then you need a new file from Dassault Systèmes or your VAR (Value Added Reseller).

4. Call Your VAR 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.

4.3. Token Expiration in 3DEXPERIENCE

For cloud-connected licenses, open the 3DEXPERIENCE Launcher. Check your "My Licenses" dashboard. If your token has expired, you will see a red banner. You must:

• Connect to the internet.
• Click "Refresh Licenses" or "Synchronize".
• Re-enter your Dassault credentials.

2.3. Network Concurrent Licenses (Floating)

In a floating environment, a central server holds a pool of licenses. Users check out a license when they launch CATIA and check it back in when they close it. The error occurs if:

• The server's license file itself has expired.
• The server's system clock has been tampered with or drifted.
• The client computer cannot communicate with the server to verify the license's extended validity.
