The protection key could not be found (hasp status 0).

When you see this error message when starting Pythagoras, it usually means that the Sentinel License Service on your computer is not running. As a result, Pythagoras cannot find the license — even though status code 0 normally indicates there’s no technical error.

The good news: this is easy to fix.




SOLUTION

Step 1: Locate the Sentinel service

  1. Open Task Manager using the shortcut Ctrl+Shift+Esc

  2. Go to the Services tab → see  1 in the image

  3. Look for 'hasplms' (Sentinel LDK License Manager) in the list → see  2  in the image

  4. Right-click on hasplms and select Restart (or Start if that’s available) → see  3 in the image


Wait a few seconds for the service to start.

Task Manager Services hasplms





What if 'hasplms' doesn’t appear in the list?

That usually means the Sentinel license software is not (properly) installed.

  1. Fully close Pythagoras

  2. Download the latest Sentinel Runtime (driver) here:
    https://www.pythagoras.net/content/uploads/sites/2/cpt-downloads/HASPUserSetup.exe

  3. Right-click the file and choose 'Run as administrator'

  4. After installation, restart your computer

hasplms service should now appear in Task Manager and start automatically.





Step 2: Check if the license portal is working


If you see the Sentinel Admin Control Center page with tabs like 'Sentinel Keys' and 'Products', then the service is working again.


Example:



Step 3: Restart Pythagoras

After completing these steps, the error message should no longer appear, and Pythagoras should launch as expected.
