title: install numpy.exe silently with batch file in windows
body: <p>I want to create a batch file that helps multiple users install numpy on a Windows shared drive. Basically, users should not have to input options or perform any actions at all (as they would if they double-clicked the numpy executable installer).</p>
  
  <p>A Python installation is <strong>already present</strong>. The users have to just run the batch file and install numpy into the default <code>Python\Lib\site-packages</code> location. </p>
  
  <p>I've tried using the following commands:</p>
  
  <pre><code>numpy-1.6.1-win32-superpack-python2.7.exe /qn
  numpy-1.6.1-win32-superpack-python2.7.exe /quiet
  numpy-1.6.1-win32-superpack-python2.7.exe /passive
  </code></pre>
  
  <p>In all cases, the batch file is in the same directory as the executables and a graphical window pops up where the user has to click 'Next' again and again. Is there a way to run the install with ALL default options and not have user interaction?</p>
