title: oracle 11g odbc drivers installation on windows 7 oracle odbc driver with the same name already exists
body: <p>these are the steps:</p>
  
  <ol>
  <li>downloaded: instantclient-basic-windows.x64-11.2.0.3.0.zip</li>
  <li>extracted to c:\instant_client_11_2</li>
  <li>downloaded: instantclient-odbc-windows.x64-11.2.0.3.0.zip</li>
  <li>extracted to c:\instant_client_11_2 (the same dir from step 2)</li>
  <li>via cmd: odbc_install</li>
  <li>getting "oracle odbc driver with the same name already exists"</li>
  </ol>
  
  <p>i've tried with instantclient-basiclite-windows.x64-11.2.0.3.0 in step 1 instead. getting the same error</p>
  
  <p>Interesting facts: </p>
  
  <ul>
  <li><p>i had the XE edition installed too, uninstalled it, deleted manually the C:\oracleXE folder, rebooted, retried steps 1-6 and still no joy. As far as i can tell there is no other oracle product (besides java) running on my machine.</p></li>
  <li><p>Using windows 7 </p></li>
  </ul>
  
  <p>Thanks.</p>
