title: Add SSIS to existing SQL Server instance
body: <p>I am trying to add Integration Services an existing SQL Server 2008 instance. </p>
  
  <p>I went to the SQL Server Installation Center and clicked the option to "New installation or add features to an existing installation." 
  At this point, a file system window pops up. I am asked to browse for SQL Server 2008 R2 Installation Media.</p>
  
  <p>I tried <strong><em>C:Program Files\MicrosoftSQLServer</em></strong> but got the error message that it was not accepted as a "valid installation folder." I went deeper into the MicrosoftSQLServer folder and found <strong><em>\SetupBootstrap</em></strong> but this was not accepted either.
  It appears that the only way to proceed is to find the Installation Media Folder but I'm not exactly sure what it's asking for.</p>
  
  <p>How can I find the Installation Media folder? Alternatively, other methods for adding SSIS to an existing instance of SQL Server 2008 are welcome.</p>
  
  <p>Thanks.</p>
