What is the expected behavior?
Desktop apps (and mobile ones) made with Chrome are not a bad idea. Perhaps Web Store wasn't the best way to ship them. 

It'd be great for Chrome-based apps to be shippable without the Web Store, submittable to Windows/macOS/Ubuntu app stores as individual apps.

There's already Electron, but Chrome apps could be cool too, especially if it would be easy to make them standalone and not coupled to Web Store.

What went wrong?
It's not implemented yet (AFAIK).

OS Version: OS X 10.13.4
Flash Version: 

There could be a feature of Chrome apps that detects if Chrome is already installed, and would then use the installed version for runtime. If it isn't installed, Chrome could be installed transparently (the runtime, not the UI). Chrome (the web browser) could itself rely on the runtime if it is already downloaded.

This could be awesome.
