title: The filename, directory name, or volume label syntax is incorrect - virtualenvwrapper
body: <p>I have virtualenvwrapper-win installed with python3.6 on win7.
  When using it, and providing path to another version of python I get these error messages:</p>
  
  <pre><code>&gt; mkvirtualenv mynew_env --python=d:\python\python35\python.exe
  Running virtualenv with interpreter d:\python\python35\python.exe
  Using base prefix 'd:\\python\\python35'
  New python executable in C:\Users\Bob\Envs\mynew_env\Scripts\python.exe
  Installing setuptools, pip, wheel...done.
  The filename, directory name, or volume label syntax is incorrect.
  The filename, directory name, or volume label syntax is incorrect.
  The filename, directory name, or volume label syntax is incorrect.
  </code></pre>
  
  <p>How do I fix it?
  I tried different slashes in the path to my python installation: backslashes, forward slashes, double backslashes, the result is always the same.</p>
