Can not get Kodi to reinstall after uninstalling it

Hi – I am new to Kodi.

Kodi Jarvis was working, then I did something and it was not working properly – so I uninstalled it, restarted my computer and tried to reinstall it again.

But I could not get past “Install fusion from zip file” – the only option it would allow me was “Cancel”.

Can someone please give me instructions on how to uninstall Kodi completely so that I can start from scratch again and reinstall Kodi?
