When you start the python interpreter, does the first message show 64 bit (AMD64) or 32 bit (Intel)? — robots.jpg

As mentioned by the other fellow, make sure you have a 64-bit Python AND a 64-bit wxPython version downloaded. If one or the other is 32-bit, it won't work. Personally, I have never had any problems installing wxPython on Windows.
