EventBroker failed to start with the below error (possibly due to .Net compability):

Application: Unify.Service.Event.exe

Strange enough, .Net version in the machine is 4.6.1. When running command line debugging, the error is:

D:\Program Files\UNIFY Solutions\Event Broker\Services>Unify.Service.Event.Debug
