My laptop changed, so wanted to get back to the setup I had before, been through enough trouble to get Windows Live Writer to be installed on my machine. You wish it is a MS baby, single installable, double click and boom!! Everything is installed completely.
Otherwise Windows Live Installer uses Windows Installer, Automatic Updates and all underlying component. Not sure why?
It uses so many components and piece in background to make it work. Basically, the installable can install any or a lot more components on your machine than required. Found garmahis.com (Thanks to Michael Garmahis) where I could get a standalone installable. There is another one if you like ... here.
