title: Python PIP cannot find pywin32 (on windows)
body: <p>I have installed python 3.5, and need to install pywin (pywin32)</p>
  
  <p>however, pip cannot find it.  Note, i have just PIP install'ed send2trash and gitpython successfully</p>
  
  <pre><code> Could not find a version that satisfies the requirement pywin32 (from versions: )
  </code></pre>
  
  <p>A few possibly relevant data points:</p>
  
  <ul>
  <li>new install of python 3.5</li>
  <li>windows 7 x64</li>
  <li>python 2.7 was previously installed on the machine</li>
  <li>as mentioned, several other packages were installed fine via PIP</li>
  <li>running these commands from git-bash, which came from the git windows installer, installed some time ago.
  -- I have gnu grep in my path, so i believe i selected the git installer option to put the whole mysys toolchain in my path</li>
  </ul>
  
  <p>full --verbose output:</p>
