body: <p>In my code i am using configparser. Everything working fine, but after i do fresh install of windows 10, this error appears: <code>ImportError: No module named configparser</code>.</p>
  
  <ul>

  In same code i do "<code>import os</code>" and this is working. Configparser is in same directory.</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>configparser is here:</p>
