Installing Chrome extension simultaneously with desktop app

[Jonas Friedwick]

I'm developing a Chrome extension and desktop app that work together. I'd like to let users download them simultaneously, which I believe is possible based on the Alternative Distribution Options in the extension docs. I think the user would download the desktop app, which would automatically install the Chrome extension. But I can't find any examples, so I'm not sure if it works. The only similar case I've found is LastPass' universal installer, which claims to download extensions on all system browsers at once. This doesn't seem to work in Chrome though -- even when I restarted Chrome, I didn't see the extension.

So I really have a few questions:

1. How can I let users download them simultaneously?
2. The docs say when this happens, the user has to manually enable the extension for it work and appear in the toolbar. What's the easiest way to have the user do this? (The only time I've seen this, it was very inconvenient -- nontechnical users probably wouldn't know how to do it.)
3. Do you know of any examples of installing such an "external extension", as the docs call it?

I would appreciate any and all help, thanks!
