Pyflakes and IPython does not work for Emacs on Windows?

[Dsrt Egle]

Hi,

With Python on Windows, I tried to use Emacs as the programming
environment. For syntax checking I installed pyflakes, but flymake
always reports "fail to launch. No such file or directory: pyflakes"
when opening a Python file. Is pyflakes not for Windows? What Python
syntax checking tools work for Emacs on Windows?

I can't invoke IPython by Emacs on Windows, either. Looks ipyhon.el
only works for Linux?

Thanks for your comments
