System.NullReferenceException at application startup under Win8.1

[MagicAndre1981]

Directly at start, I get this System.NullReferenceException:

[Success] Name WMIWatcher
[Success] ServiceName WMIWatcher
Topshelf v4.3.0.0, .NET 7.0.0 (7.0.0)
The WMIWatcher service is now running, press Control+C to exit.
Unhandled exception. System.NullReferenceException: Object reference not set to an instance of an object.

Under Windows 10 it starts and displays WMI activities.

Try v 1.0.6.0 which should fix the issue.
