- Confirm correct server name and port in client license settings (default port often 5053 or as specified).
- Restart the FlexNet (or Zemax) license service on the server.
Key Characteristics:
- Persistent binding: The license is locked to the computer’s hardware fingerprint.
- No network dependency: Unlike floating licenses, fixed licenses do not require a continuous connection to a license server.
- Offline capability: Once activated, the software can run entirely without an internet connection.

- User submits
hostid to Zemax portal → receives license.xml.
- ZLM ingests
license.xml → writes encrypted entitlement to C:\ProgramData\Zemax\Licenses (Windows) or /opt/zemax/licenses (Linux).
- No background service required – OpticStudio reads the file directly at launch.
