License Not Found Error 30 in ETABS 2016: Causes, Diagnosis, and Resolution

The Fix:

  1. Temporarily disable your antivirus and Windows Defender Firewall.
  2. Reinstall the Sentinel drivers (Step 2).
  3. Add exclusions to your antivirus for:
    • The ETABS 2016 installation folder (e.g., C:\Program Files\Computers and Structures\ETABS 2016\)
    • The licensing folder (C:\ProgramData\SafeNet\)
    • The process hasplms.exe (Sentinel License Manager)
  4. Re-enable your antivirus.

The Correct Order:

  1. Uninstall ETABS 2016 from Control Panel > Programs and Features.
  2. Uninstall Sentinel RMS License Manager and Sentinel LDK Run-time.
  3. Delete leftover folders:
    • C:\Program Files\Computers and Structures\ETABS 2016\
    • C:\ProgramData\SafeNet\
    • C:\ProgramData\Sentinel\
  4. Clean the registry (optional but helpful):
    • Press Win + R, type regedit, navigate to HKEY_CURRENT_USER\Software\Computers and Structures and delete the ETABS 2016 key.
  5. Restart your PC.
  6. Reinstall ETABS 2016 (Right-click installer > Run as Admin).
  7. Reinstall the latest Sentinel drivers.
  8. Apply your license file or plug in your USB key.

Step 5: Network License-Specific Troubleshooting

If you use a network license (floating license) and see Error 30, the issue is often the lservrc file format.

  1. Open your lservrc file in Notepad. It should contain a single line formatted as:
    • For server name: SERVER=YourServerName ANY 27000
    • For IP address: SERVER=192.168.1.100 ANY 27000
  2. Ensure port 27000 (or whatever port your admin set) is open in Windows Firewall on both the server and your local machine.
  3. On your local machine, set the environment variable:
    • Right-click This PC > Properties > Advanced System Settings > Environment Variables.
    • New System Variable:
      • Variable name: LSHOST
      • Variable value: YourServerName or YourServerIP
    • Restart ETABS.

Solution 3: Reinstall Sentinel RMS License Manager

  1. Uninstall the existing “Sentinel RMS License Manager” from Windows Control Panel.
  2. Restart the computer.
  3. Download the latest version (from CSI’s official website – typically version 9.x or higher for ETABS 2016).
  4. Install with administrative privileges.
  5. Reconfigure the license (point to the license file provided by CSI).
