TestComplete uses the Sentinel LDK License Manager service to activate licenses and to manage and verify license information. If the service is not running, TestComplete cannot check it and therefore cannot start, or, if the license has not been activated yet, it cannot complete the activation. The service is started automatically after TestComplete is installed and automatically starts every time the operating system loads. You receive this error message because the service is stopped or is not running properly.
To ensure that the Sentinel LDK License Manager service is running:
-
Open the Control Panel | Administrative Tools | Services applet.
-
Select the Sentinel LDK License Manager service in the list.
-
Right-click the service and select Start or Restart from the context menu.
Once the service is running, click Try Again to close the message box.
If the service does not start or if it is not in the list, reinstall TestComplete.
