Error 0x800401e3 bei Verwendung in einem Windows Dienst

Hallo;
ich will die ZENON Runtime von einem Windows Dienst aus via COM in C++ ansprechen.
Wenn ich den Dienst als Konsolenanwendung starte, dann funktioniert alles einwandfrei. Führe ich die selbe Anwendung aber tatsächlich als Dienst aus, dann kann ich das Application Objekt nicht instanzieren.
IApplicationPtr::GetActiveObject("zenon.Application") liefert den COM error 0x800401e3.
Ich habe schon einiges probiert (OpenWindowStation(), Security, etc.), komme aber nicht weiter. Kann mir da wer helfen?
Danke!
