title: SQL Server DTA Missing
body: <p>Slightly OT, but...</p>
  
  <p>I have two named instances of MSSQL 2008 Developer Edition and also SQL Express 2008 with Advanced Services.</p>
  
  <p>I just went to use the DTA, and it is not anywhere on my system.</p>
  
  <p>I went to setup to add it, and see that the checkbox for it is cleared (all others are checked), and it and every other shared tool is greyed out so I can't get it installed.</p>
  
  <p>Before I uninstall all of this stuff, can anyone recommend a way to get this stuff installed.</p>
  
  <p>Thanks.</p>
