ImportError: DLL load failed in _core_, while launching demo.py

[Richard.Nault]

PROBLEM:
ImportError: DLL load failed: %1 is not a valid Win32 application
in _core.py", line 4, in <module>
while launching python demo.py

NOTE: I just installed wxPython

ENVIRONMENT:
Windows Vista family premium 64-bit, SP2
Python 2.6.1 (r261:67517, Dec 4 2008, 16:51:00) [MSC v.1500 32 bit
(Intel)] on win32
I installed
wxPython2.8-win64-unicode-2.8.10.1-py26.exe
in C:\Python26\Lib\site-packages\wx-2.8-msw-unicode\wxPython
and
wxPython2.8-win32-docs-demos-2.8.10.1.exe
in C:\Program Files (x86)\wxPython2.8 Docs and Demos\

I set PYTHONPATH=C:\Python26\Lib\site-packages\wx-2.8-msw-unicode
\wxPython


FULL ERROR MESSAGE:

Solution: Do not run the 64-bits version of wxPython over Python 32-
bits.

I reinstalled
Python v2.6.4 (python-2.6.4.msi)
wxPython 2.6 (wxPython2.8-win32-ansi-2.8.10.1-py26.exe)

demo.py works fine now.
