Could not load file or assembly 'System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.

I downloaded the web app from my company's server and running it on my machine. It works well except when I click on one of the menu items (all the others are good). It is showing me this error. I checked my web.config and the version I set for web.mvc is 4.0.0.0. I have no idea how is this happen.

I checked the similar problem on the websites but the solutions are not working for me. Here is the assembly load trace info that might be helpful:

Assembly Load Trace: The following information can be helpful to determine why the assembly 'System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' could not be loaded.

I am really confused that I am using MVC4 but the error message is version of 3.0.0.0. This problem has annoyed me for a long time. Please help me and thanks in advance.

Problem solved by installing MVC 3.0 in my computer. Now it's working.

On your web.config, be sure to have this inside assemblyBinding section

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

It forces to use 4.0.0.0 no matter what assembly version is trying to bind
