title: How to tell which driver is being used by SQL Server?
body: <p>I have "inherited" a computer that has multiple ODBC driver's installed on it. Before I go removing anything, how do I tell which driver SQL Server is actually using? Does it just use the most updated one? </p>

  <p>I am running SQL Server 2014, version 12.0.5207.0 (64 bit). I am also using SQL Server Management Studio 2017, version 17.5.</p>
  
  <p>Additional question - I am planning to update the ODBC driver to 13.1, would I install the 64 bit since the server is 64 bit? When I look at the ODBC data sources the drivers are installed in both the 32-bit and 64-bit dialogues, so I am a bit confused. Total noob question, I realize, but I am very new to this.</p>
