title: Installing SQL Server 2012 Developer after uninstalling expired Evaluation
body: <p>I installed the Evaluation Edition of SQL Server 2012 and it has expired. I uninstalled the trial, rebooted, and installed the Developer Edition. It said it installed successfully; however, when I open SQL Server Management Studio it won't open and I get the message:</p>
  
  <blockquote>
    <p>Evaluation period has expired.</p>
