Manage NuGet Packages not visible on menu

Question

Using Visual Studio 2012 Premium on Win 7 x64, I make a new project (an MVC 4 project). When right-clicking on the project, I see no 'Manage NuGet Packages' option. A packages folder exists in the solution directory, as does a package.config file in the project directory. When going to Tools, there is no Manage NuGet Packages option, either. When going to Tools->Extensions and Updates..., the NuGet Package Manager is installed and up to date.

Any idea why my project is unable to manage the NuGet packages for itself?

Here's a screenshot of the menu:

I had a similar problem. The problem was next: I've installed NuGet Packager instead of NuGet Package Manager (from Extensions and Updates). Once I've installed the last one, it appeared in the context menu. Maybe you faced the same problem.
