Can’t delete Jarvis to install Krypton

Hi
Currently have Jarvis 16.1 installed on my laptop while using windows 8.1 then updated it to Windows 10 and Jarvis ‘seemed’ to be working as usual. Used kodi.tv to download Krypton17.1 BUT when I open Kodi it shows the Krypton logo first then shows Jarvis 16.1

I’m a very newbie need and help don’t understand coding or anything

WINDOWS 10 HOME EDITION
64 BIT OPERATING SYSTEM
X64-BASED PROCESSOR

Can anyone help please?
