How to restart FineReader Engine after a crash on Linux


After a crash, FineReader Engine cannot be initialized and the error message "Failed to run license. There are no free licenses." is displayed.



While the software that utilizes FineReader Engine is running, the Licensing Service does not allow the license to be used again by locking it. In case of a crash, the Licensing Service would still be running keeping the license locked.



The issue can be resolved in several ways.

  • Restarting the machine will also restart the service and allow to start the Engine again.
  • The Licensing Service can be restarted manually to release the license by executing the following command via the command line:
     systemctl restart abbyy-fre12-licensing-service.service
