32 bit builds are already uploaded. Try the regular version first. If that doesn't work, try the nwjs version. The NWJS version is much bigger in size, so if you can make the regular version work, choose that one instead.
Node Web JS. Basically the way it works is it allows you to run a local copy of the web game as if it were an application (but in reality it's just a browser running the web game). It bundles chrome so compatibility should be better, but the size is much bigger (since chrome is included). Use the regular version first, as that uses the built in windows browser, so you only download the game. If it doesn't work (for older windows maybe), then try nwjs.
