title: SQL instance specified is not supported by installed version of TFS
body: <p>I have installed Team Foundation Server 2013 Update 5. I am already running MSSQL 2008 R2 and MSSQL 2012. But when I tried to install my TFS it gives the following error in <strong>Readiness Check</strong> for <strong>Basic</strong> Setup Wizard.</p>
  
  <blockquote>

  <p>Before this I had TFS 2013 Update 2 which was running fine but out of nowhere it started giving following error on accessing it from my VS2013 Update 4:</p>
  
  <blockquote>
    <p>HTTP: 500 Internal Server Error</p>
  </blockquote>
  
  <p>So then I uninstalled the previous version and installed the Update 5 but the Data Tier error mentioned above is continuously appearing. Then I installed MSSQL 2014 but the error is still there. </p>
