title: PyQt5 on Windows in Python 2.7: Error importing QtWidgets
body: <p>I downloaded PyQt5 executable file on Windows 7 for python 2.7 both 64bit versions.</p>
  
  <p>Is installed on C:\Python27\Lib\site-packages\PyQt5</p>
  
  <p>I'm trying to use the above code:</p>
  
  <pre><code>from PyQt5.QtWidgets import QApplication, QDialog 
  </code></pre>
  
  <p>I get the error:</p>
  
  <pre><code>ImportError: DLL load failed: The specified module could not be found.
  </code></pre>
  
  <p>I found the QtWidgets on this folder: <code>C:\Python27\Lib\site-packages\PyQt5\sip\PyQt5\QtWidgets</code></p>
  
  <p>Do you have any idea?</p>
