As I believe others have mentioned, 'pythonw' is not the one you want
to use 99% of the time.  'pythonw' is a 'win32' app rather than a
'console' app, meaning that it has no attached console, and if you
just run it with no arguments, it will appear to do nothing (though
actually, it starts, finds it has no input, and ends very quickly).

You hit upon a bug in 3.5.0b4, which is that the installer is broken
for tkinter unless you have Microsoft Visual Studio 2015 installed.
See http://bugs.python.org/issue24771 for details, the fix will be
included in 3.5.0rc1.

Your best bet is to avoid using pre-release software, and stick with
Python 3.4.3 until such time as 3.5.0 final is released.

Hope this helps,
