Does all non-Python stuff seem to be working?

In Command Prompt, 'python -m idlelib' should run Idle and display 
(without disappearing) any available error messages.

Idle imports tkinter which imports threading. If that fails, Idle never 
visibly starts.  If the imports succeed, and Idle starts, but cannot 
connect to a subprocess, it displays a message in Shell. (I have 
occasionally seen this, but close Idle and retry always works.)  Your 
description suggests the former.

Does 'python' itself start. If so, and you get interactive prompt, does 
'import threading' work?  Ditto 'import tkinter'?  If so, does 
'tkinter.Tk()' bring up an empty tk window?

Back at interactive prompt, what happens with 'python -m test'?  There 
are a couple of modules that may sometimes fail, but the rest should not.

Upgrading on top of broken Python may not work. If the tests above fail, 
re-install after un-installing.  Un-installing will leave /python34 but 
only with things you added (or separately installed). You may need to 
're-install' 3.4.0 to un-install.
