how to install 17.1

ok this may sound dumb but i have been trying to install 17.1 for a week and i go to download at the top right corner of the page and nothing happens. so i go down a bit to the spot that says windows etc and i pick andrion because i have a kodi box, i scroll down to the selections and i pick android for my kodi box i then get directed to google app store and it show 17.0. so do i hve to uninstall that app then try reinstalling it? i have a backup so i can restore back to what i will loose. thanks
