title: windows Pycharm project interpreter nothing to show
body: <p>I was using Pycharm in windows and when I tried to check my project interpreter and clicked <strong>install packaging tools</strong>, something happened wrong.</p>
  
  <p><img src="https://i.stack.imgur.com/16Hry.png" alt="enter image description here"></p>
  
  <p>The error turned out:</p>
  
  <blockquote>
    <p><em>error:[WinError 32] The process cannot access the file because it is being used by another process: 'c:\users\Username\anaconda3\lib\site-packages\setuptools-39.1.0-py3.6.egg'</em></p>
  </blockquote>
  
  <p>I followed some tutorial online to upgrade my pip and setuptools, pip is now 10.0 and setuptools 47.1.1, but every time I open the settings, all the way same and the <strong>'setuptools-39.1.0-py3.6.egg'</strong> keeps showing up even I delete it each time.</p>
  
  <p>I was running under python 3.7, Pycharm 2018.03, Anaconda 5.4. Thanks for help!</p>
