Estoy intentando lanzar mi aplicación directX / SharpDX conDeviceCreationFlags.Debug pero estoy recibiendo el siguiente bloqueo en el inicio:

SharpDX.SharpDXException: HRESULT: [0x80004005], Module: [General], ApiCode: [E_FAIL/Unspecified error], Message: Unspecified error

at SharpDX.Result.CheckError()

at SharpDX.Toolkit.GamePlatform.Run(GameContext gameContext)

Esto está en Win7 32bit y tengo el SDK de DirextX de junio de 2010 y el Tiempo de ejecución instalados, así como el SDK de Windows para Windows 7.

por cierto, esta pregunta se originó a partir de éste:SharpDX se bloquea al representar video h264 usando MediaFoundation
