Somebody reported this today:

File "C:/Python27/kivyhello.py", line 4, in <module>
     from kivy.app import App
   File "C:/Python27\kivy\app.py", line 316, in <module>
     from kivy.base import runTouchApp, stopTouchApp
   File "C:/Python27\kivy\base.py", line 30, in <module>
     from kivy.event import EventDispatcher
   File "C:/Python27\kivy\event.py", line 8, in <module>
     import kivy._event
 ImportError: DLL load failed: %1 is not a valid Win32 application.

----------------

The problem was that they needed to set their PATH properly so kivy could be found.

Couldn't we generate a more informative error message here?
Is the %1 even correct?
