title: How to set the proper Python version when creating a virtual environment using virtualenv on windows?
body: <p>I want to use python 2.7 instead of python 3, which is used by default (note that I have them both installed on my computer already).
  So I tried what I saw should be the right thing to do, that is:</p>
  
  <pre><code>python -m virtualenv my_env -p "\Program Files (x86)\Python27\pythonw.exe"
  </code></pre>
  
  <p>and I receive the following message:</p>
  
  <pre><code>Running virtualenv with interpreter \Program Files (x86)\Python27\pythonw.exe
  </code></pre>
  
  <p>That doesn't look so much like an error to me, but yet, no environment is created. Can someone help me with that?</p>
