Create a new controller - error starting the selected code generator

Question

I am using Visual Studio Express 2013 for the web (specifically version 12.0.21005.1 REL). This is my first project using VS2013, I have used VS2012 until now.

I am trying to create a new controller in my asp.net MVC application. I am using Entity Framework 5 with the first code (.NET 4.5). I want Visual Studio to create a template for me (you know, a controller with views for reading / writing / deleting, etc., Instead of writing code myself from scratch).

However, every time I try to create a controller, I get the following error message:

Is there some kind of error in VS 2013? I cannot understand what this means, and restarting VS2013 does not help.

            public string EnrollmentName { get; set; }
            public string Credits { get; set; }
        }

        // Create the class that inherits from DbContext
        // The name of this class is also used as the connection string in web.config 
        public class EFDbContext : DbContext
        {
            public DbSet<Student> Students { get; set; }
            public DbSet<Enrollment> Enrollments { get; set; }
