how to run with 2016 nwjs webkit

[abulka]

Tried running with 2016 nwjs webkit using nwjs.app/Contents/MacOS/nwjs interface.editor/ and got a window OK with some layout and text but it crashed on:

GVA info: Successfully connected to the Intel plugin, offline Gen9 
chrome-extension://iemobogkdikhjdjgiejaeojobmnjdifn/index.html:144
Interface.Editor = {
^

ReferenceError: Interface is not defined

Not sure if NW.js has evolved too much since this interface editor was written - or if there is a simple fix?

P.S. I downloaded the 'normal' build of nw which just is a single file nwjs.app and my dir structure looks like:

interface.editor/
nwjs.app

and the npm installs all worked ok.
