  <p>No matter what i do, it won't install. It gives me some error :</p>

  </ol>
  
  <p>I have tried searching everything on web, couldn't find any specific solution. </p>
  
  <p>Some blogs say that it has to be Visual Studio Update 4 and not Visual Studio with update 4, will i have tried both. None of them seems to be working.</p>
