Upgrade to the latest 2.7 or even 3.3 if at all possible.

On my Windows 2.7 installation, directory /Lib contains directory 
/lib-tk (which is added to the path). /lib-tk contains files Tkinter.py 
and ttk.py, among others. If you have ttk.py, then I do not think you 
should get that specific message; if there were a problem finding 
tcl/tk, it should say something else. If you do not have that file, as 
it seems, then your installation is incomplete. So check your 
/Lib/lib-tk. If you do not know where it is

import sys
print(sys.path)

Portability note: In 3.x, /lib-tk was renamed /tkinter and removed from 
the path. Tkinter.py was renamed __init__.py to make the renamed 
/tkinter an importable package. So 'import Tkinter becomes 'import 
tkinter', while 'import ttk', etcetera, is now 'import tkinter.ttk', 
etcetera. 2to3 should make the fixes.
