title: Cx_freeze is not working on Win 10 with Python 3.6.2
body: <p>I am starting to learn a bit about Python. I am trying to convert Python Tkinter app into exe file. Converting to exe works fine when Tkinter is not involved. I tryed sample file of setup.py and Tkinter app that you can find on official website of cx_Freeze [<a href="http://cx-freeze.readthedocs.io/en/latest/index.html]" rel="nofollow noreferrer">http://cx-freeze.readthedocs.io/en/latest/index.html]</a> but still geting a lot of errors [like: <code>KeyError: 'TCL_LIBRARY'</code>] in CMD when runing build command. On official website is stated that Python 3.6 is supported.  </p>
  
  <p>Here is official example of setup.py:</p>
  
  <pre><code>import sys
  from cx_Freeze import setup, Executable
  
  base = None
  if sys.platform == 'win32':
      base = 'Win32GUI'
  
  executables = [
      Executable('app.py', base=base)
  ]
  
  setup(name='simple_Tkinter',
        version='0.1',
        description='Sample cx_Freeze Tkinter script',
        executables=executables
        )
  </code></pre>
  
  <p>And here is official example of test Tkinter app:</p>
  
  <pre><code>#!/usr/bin/env python
  # -*- coding: utf-8 -*-
  
  try:
      from tkinter import Tk, Label, Button, BOTTOM
  except ImportError:
      from Tkinter import Tk, Label, Button, BOTTOM
  
  root = Tk()
  root.title('Button')
  Label(text='I am a button').pack(pady=15)
  Button(text='Button').pack(side=BOTTOM)
  root.mainloop()
  </code></pre>
