title: MVC 3 is installed but not showing up in Visual Studio
body: <p>ASP.NET MVC 3 is installed. I know this because of the output.</p>

  <p>When I try to open an MVC 3 project in Visual Studio 2010 Professional, I still receive the "The project type is not supported by this installation." </p>
  
  <p>The project has these three ProjectTypeGuids:</p>
  
  <ul>
  <li>{E53F8FEA-EAE0-44A6-8774-FFD645390401} <strong>ASP.NET MVC 3.0</strong></li>
  <li>{349c5851-65df-11da-9384-00065b846f21} <strong>Web Application</strong></li>
  <li>{fae04ec0-301f-11d3-bf4b-00c04f79efbc} <strong>C#</strong></li>
  </ul>
  
  <p>I have used the Web Platform Installer to install <strong>ASP.NET MVC 3 (Visual Studio 2010)</strong>. </p>
  
  <p>Further, I have already seen this <a href="https://stackoverflow.com/questions/2745988/the-project-type-is-not-supported-by-this-installation">The project type is not supported by this installation</a> and tried most of the solutions. </p>
  
  <p>Of note is that I have both Visual Studio 2010 Professional and 2012 installed Professional. </p>
