On Windows the solution for this is ClickOnce[1]. It's actually really well done, but I've only ever seen one program use it - Chrome[2].

I don't think Google Chromium (Chrome) uses the .NET ClickOnce installer but Google's own Omaha software installer

He's referring to a special launcher for the installer that's used on Windows.

The only problem is that ClickOnce has a .NET dependency, but if you can get around that, you're home free.
