Opening Kodi zip file

Ok. I’m pulling my hair out on this one. Trying to update kodi from Jarvis to Krypton 17.1. I got the zip file in es file explorer, but I cannot get it to open. I have done it a couple of times, and I get a message onscreen that says file
Saved in emulated. But after that, I’m lost! Can ya help a brutha? I feel like this should be simple, and like I’m going to feel stupid when you explain it to me, but please…..help!
