deleted movie maker files/folders now i can’t download it!!

I used to have windows live movie maker on my windows 7 computer I updated it to movie maker and it was all fine,but in an attempt to get windows live movie maker back I deleted movie maker completely from my computer,including all the folders and files which contained it,then when I tried to get it back,using windows essentials,it installs and just says 'done' but movie maker is not anywhere on my computer,or my downloads or anywhere!i've tried everything and I can't get it back,it's something I need as we'll! Is it because I deleted the folders?help!?
