When starting, AQTime connects to the Sentinel LDK License Manager service running on the AQTime computer and requests permission to run. If the License Manager permits the run, AQTime continues the launch, else, it displays an error message informing you about the problem.
Below are some typical causes of why AQTime can fail to find the license:
AQTime cannot start if the license has not been activated. For instructions on license activation, see Activating Node-Locked Licenses.
AQTime fails to find the license if the Sentinel LDK License Manager service is not running.
To determine whether this service is running, open the Control Panel > Administrative Tools > Services window and see whether the services list contains the Sentinel LDK License Manager service and that the service is running.
If the service is not running, try to start it. If this does not help, reinstall AQTime and try again.
