No se pudo cargar el archivo o ensamblado 'System.Web.Mvc' o una de sus dependencias

Tengo esta nueva aplicación MVC que he instalado en Windows 2008 Server. Y recibe el siguiente mensaje cuando ejecuto el localhost.No se pudo cargar el archivo o ensamblado 'System.Web.Mvc' o una de sus dependencias

He comprobado en la carpeta Bin y puedo confirmar que Systems.Web.MVC está allí. Y la versión del archivo es, 2.0.50217.0

y en el web.config he definido este montaje,

¿Puede alguien ayudar? Ver el siguiente mensaje de error:

no se pudo cargar el archivo o ensamblado 'System.Web.Mvc, Version = 3.0.0.0, ..."

su aplicación está utilizando MVC3, pero de acuerdo a su propio comentario, el servidor tiene MVC2 (2.0. 50217.0).

Tuve este problema al implementar en un servidor que ejecutó MVC2, los archivos que deberán incluirse en la compilación son:

Microsoft.Web.Infrastructure.dll 
System.Web.Helpers.dll 
System.Web.Mvc.dll 
System.Web.Razor.dll 
System.Web.WebPages.Deployment.dll 
System.Web.WebPages.dll 
System.Web.WebPages.Razor.dll

me encontré con este problema en el servidor 2012 que didn' t tiene .NET Framework 3.5 (que también incluye 2.0 y 3.0). ¡Así que revisa eso también! –

Si usted tiene los derechos para hacerlo, puede download e instalar MVC3 en tu servidor web.

Haga clic derecho en System.Web.Mvc en su carpeta de referencia y asegúrese de que copy local esté establecido en verdadero. Eso debería agregar System.web.mvc a su carpeta bin y debería corregir el problema.
