Configurators that communicate with a desktop application won't work when running Switch as Windows service. This is due to a Windows limitation. Desktop applications cannot be started by a Windows Service, hence their configurators cannot be used either.
Some background information
Since the introduction of Windows Vista, Microsoft no longer allows applications that run as a Service to interact with the desktop. This means for example that these applications cannot show any UI to the user. As desktop applications cannot function with this limitation, their configurators do not work either.
Remark
If you want to use the configurators for desktop applications, you must run Switch as a regular process and not as a Windows service. However, in that case, you may want Switch to start processing automatically when a user logs in. To do so, ensure that the preference Start Switch Server automatically at login is set to Yes (See Switch preferences: User interface). Remember that a user has to log in in order to start Switch, which is not necessary when running Switch as a Windows service.
