Hello. I have accidentally deleted the "Window Live" folder in C:\Program files. I tried to recover the Window live Messenger in "Add/Remove" of the control panel, which was a standard procedure stated on the net. However, I could not find "Window Live Essential" there. So I then tried to re-install Window Live Messenger by executing the "Window Live Essential 2012 set-up" (wlsetup-web.exe) downloaded from the microsoft webpage but it stated that I have already installed Window Live Messenger. Is there anyway I can fix my Window Live Messenger? Thanks!
