Important update:
NW.js versions newer than v0.72.0 may be incompatible with Windows 7 and 8/8.1.
Please see https://support.google.com/chrome/a/answer/7100626 and https://nwjs.io/blog/ for information.
As long as your game doesn’t connect to the Internet, it’s most likely safe to use v0.72.0 of the runtime in order to support these systems. I’ve added this information to the instructions.
Please note that for Linux systems, the most recent runtime without known issues is still recommended.
