Answer 1

I have fix that with this

Install-Package Microsoft.AspNet.Mvc -Version 4.0.40804 -Project <your project name>

This will automatically update Package Mvc

Answer 2

1. Remove the referenced System.Web.Mvc.dll under your project's References.
2. Add a new project Reference to System.Web.Mvc 4.0.0.1.
3. Click on the newly referenced DLL, and in the properties windows set Copy to Local to True.
4. In your project's web.config file, change the System.Web.Mvc entry to:

<dependentAssembly>
    <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.1" />
</dependentAssembly>
