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

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 ).

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

Seeing the message 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:

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

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