Impossible de charger le fichier ou l'assembly (.NET, Visual Studio 2010)

J'obtiens une erreur qui est déconcertant de m'achever. J'ai un .NET Application qui tire dans une référence à un fichier OCX utilisé pour automatiser une 3ème partie du programme. Cette application fonctionne parfaitement quand je le lance à partir de Visual Studio, mais quand je le package dans un fichier MSI et l'installer sur une machine de test, il ne parvient pas en disant "impossible de charger le fichier ou l'assembly "Interop.OISSERVERLib, ...".

Quelqu'un aurait-il des suggestions sur comment je peux gérer cela?
