Keep your Chaos tools updated, and Error 200 will become a rare sight. Last updated: 2025

If you are a user of Chaos Vantage (formerly Project Lavina), you may have encountered the dreaded License Error 200 . This error typically appears as a pop-up message when launching the software or attempting to connect to a license server, blocking you from rendering or navigating your scene.

Understanding what this error means and how to troubleshoot it is essential to get back to real-time ray tracing. Error 200 is a generic license acquisition failure code. Unlike errors that point to a specific missing file or network outage, Error 200 indicates that the Chaos Licensing client application could not retrieve a valid license from the designated source (local license server, Chaos Cloud, or enterprise license server).
