title: Oracle - Instant Client
body: <p>I'm trying to install the <em>Oracle Instant Client</em> and <em>ODBC</em> drivers on a 64 bit, <em>Windows</em> 7 machine.</p>
  
  <p>I have downloaded <strong>BOTH</strong></p>
  
  <ul>
  <li>Instant Client Package - Basic</li>
  <li>Instant Client Package - ODBC</li>
  </ul>
  
  <p>I had put both sets of files in the same directory:  </p>
  
  <pre><code>C:\Oracle\instantclient_11_2
  </code></pre>
  
  <p>I set both the <code>ORACLE_HOME</code> and <code>TNS_ADMIN</code> environment variables to the same directory: </p>
  
  <pre><code>C:\Oracle\instantclient_11_2
  </code></pre>
  
  <p>Finally, I am trying to execute the "<code>odbc_install.exe</code>" file as an <em>administrator</em>.</p>
  
  <p><em><strong>ERROR</em></strong>:  <code>Oracle ODBC driver with the same name already exists</code></p>
  
  <p>The one thing I did <strong>BEFORE</strong> any of this was to install and later uninstall the <code>OracleXEClient.exe</code> file.</p>
  
  <p>Not sure how to proceed???</p>
