Extension won't show up in menu

Getting Started with CEP Extensions > 5. Write Your ExtendScript Code lacks some info, but I assume

function openDocument() {}

goes to host/index.jsx.

After following guide by letter and putting everything to C:\Program Files (x86)\Common Files\Adobe\CEP\extensions\, extension doesn't show up under Window > Extensions

Latest Ps CC
Win 10 x64

My manifest:

Might some versions be wrong?
Any ideas appreciated
