title: Python not finding modules after installing with pip
body: <p>I have installed various third party modules with pip and they worked fine until I then ran ccleaner today. Now I cannot import any of these modules. </p>
  
  <p>I've added site-packages to the PATH variable:
  C:\Python27\;C:\Users\Rick\PythonScripts;C:\Python27\Scripts;C:\Python27\Lib;C:\Python27\Lib\site-packages\</p>
  
  <p>I can import the modules when I run python through command line, but not when I run a script or in a terminal window. They are all running the same version of python: 2.7.12 (in Windows 7).</p>
  
  <p>Any suggestions for how I can fix this?
  Thanks</p>
