how do I install Emaxima on windows?



Hi, list
(Sorry, I'm learning engish)
Coud you tell me, how do I install Emaxima on windows?, I have Maxima 
5.9.3.99rc4, Windows XP professional and Emacs 20.4.1.

I'd search for .emacs file, but I don't found it, and  too I'm learning 
about Software Libre, but on the moment I'd like install Emaxima for my 
Thesis.

Thanks, list.
