title: Pip error: Fatal error in launcher: Unable to create process using '"'
body: <p>I've seen many threads about this, and have tried all options except for completely wiping Python off of my machine and re-downloading everything...</p>
  
  <p>I'm using a Windows 10, 64-bit machine, and had already downloaded Python2.7. Commands like 'C:\>pip install seaborn' were not an issue.</p>
  
  <p>I recently downloaded Python3.6, and now my pip will not work - it returns the error in the title.</p>
  
  <p>I have added <code>C:\Python27, C:\Python36, C:\Python27\Scripts, C:\Python36\Scripts</code> to my Path, and still it won't work.</p>
  
  <p>If I type in the command <code>C:\&gt;python27 -m pip install seaborn</code>, however, the pip works. I am really confused why I can no longer just type in pip install  and have it work.</p>
  
  <p>Thanks in advance!</p>
