Amazon Fire Stick

Hello

I’m probably being stupid – I am really struggling to download Kodi after numerous attempts onto my fire stick.
I have used both of these methods… (and more)…
http://troypoint.com/how-to-install-kodi-on-fire-tv/ and adding the ‘arm’ and opening in browser method.
After the open file part, where it should take me to, install, it comes up with

Select
ES Note Editor
HTML Viewer

It has an option to set as default app, but nothing else, only to click on one which doesn’t end in installing KODI.
If anyone knows where I am going wrong or has any ideas what the possible solution is, I would be really grateful.

Thank You
