title: xlwings with python 3.5 on Windows
body: <p>I have been stuck for some time. My configuration is: <code>python 3.5</code>, <code>xlwings 0.5.0</code> and <code>Windows 7</code>. I get the following traceback while trying to <code>import xlwings</code>:</p>
  
  <pre><code> Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
    File "C:\Program Files\Python 3.5\lib\site-packages\xlwings\__init__.py", line 20, in &lt;module&gt;
      from . import _xlwindows as xlplatform
    File "C:\Program Files\Python 3.5\lib\site-packages\xlwings\_xlwindows.py", line 15, in &lt;module&gt;
      import pywintypes
    File "C:\Program Files\Python 3.5\lib\site-packages\win32\lib\pywintypes.py", line 124, in &lt;module&gt;
      __import_pywin32_system_module__("pywintypes", globals())
    File "C:\Program Files\Python 3.5\lib\site-packages\win32\lib\pywintypes.py", line 117, in __import_pywin32_system_module__
      assert sys.modules[modname] is not old_mod
  AssertionError
  </code></pre>
  
  <p>After some search on the internet, my understanding is that the problem comes from pywin32 'known problems', but I am not sure what it is all about. Can you help, please?</p>
