I am also facing the same issue..
Also, when I am restating the services, QlikSense Engine service shows 'Stopping...' but doesn't really stop or restart.
Can It be because of the issue with QlikSense Service Dispatcher.
The description for Event ID 300 from source Qlik Sense Service Dispatcher cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
Did anyone get any resolution for the issue?
