MSN under Windows XP 64bit.

1) Download the full installer from Microsoft:
http://download.live.com/?sku=messenger

It should be named "wlsetup-all.exe" (not the web version "wlsetup-web.exe), try several times then you will get it.

2) Use this patcher at your own risk :-) I tried it and works..

3) Launch the patched installer

4) Enjoy...
