title: Visual Studio 2008 The project type is not supported by this installation
body: <p>I know this question has been asked before but none of the solution given seem to have resolved my issue. </p>
  
  <p>I am using visual studio 2008 professional addition. When I try open a project (.sln file) I get the below error:</p>
  
  <p>'.csproj' cannot be opened. The project is not supported by this installation. </p>
  
  <p>I understand it has some to do with the "GUIDS" on my csproj file which are below:</p>
  
  <pre><code>&lt;ProjectGuid&gt;{7C77DC9C-1EE5-4539-A12A-3F9F25813D8F}&lt;/ProjectGuid&gt;
  &lt;ProjectTypeGuids&gt;{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}&lt;/ProjectTypeGuids&gt;
  </code></pre>
  
  <p>What do I do with this information? I has installed MVC's 1, 2 and 3 (scatter gunb approach) and have SP1 installed but still getting the same error. I ran devenv /setup in the command line, which didn't appear to do anything. </p>
  
  <p>Any ideas?</p>
