L'automatisation de Pare-feu Windows avec

J'ai le C# une Application qui utilise le PORT 777 pour la communication asynchrone et le PORT 3306 pour la communication avec Mon Serveur Sql. Les problèmes surviennent lorsque les ports est bloqué par un pare-feu. J'ai essayé de créer un programme pour ajouter une exception dans la liste du pare-feu de Windows 7.

Quand je lance le programme, j'obtiens bug comme suit: "l'échec Catastrophique (Exception de HRESULT: 0x8000FFFF (E_UNEXPECTED))".

Je ne comprends pas ce que ces erreurs veux dire, toute suggestion est la bienvenue, Merci.
