- if you still have a windows machine with it installed, check the windows folder doing a quick search - try doing the windows updates till you get to that part, after the dowload is complete before it start installing do a quick search on the windows folder again - if you find it you can probably copy it and try running with a switch Install_WLMessenger.exe /Silent or maybe install 7zip and right click the exe open archive to see whats inside it, if it has an installer just for messanger maybe
