Can I compile/package a Node-Webkit (NW.js) app into an exe for windows and a version for Linux?

I've looked on the Node-Webkit site and it appears to say that I can make an application with HTML5 and compile it for Windows, Linux of Mac so it will run without the need for the user to install Node.js separately. However, when I try their sample apps (e.g. http://ift.tt/1BUV7HG found on the official NW.js page: http://ift.tt/1G6MZdi ), the ".exe" file does not run the app (on either Win 7 or XP). It just opens a simple browser window with the address "nw:blank" and a gray page says "NW.JS" and does nothing.

Can these apps be packaged and run without requiring the user to install node.js?
