If you really want WLM 2009 you can get the offline installer from here http://g.live.com/1rewlive3/en/wlsetup-all.exe

It's about 134MB download. I use 2009 version of WLM because it's simple and works well, and none of the awful ribbon crap. I keep the offline installer on external drive cos I'm sure it will dissapear one day, microsoft don't seem to like people using older versions of anything.
