Close and restart application during uninstall/reinstall does not work

[ndench]

Thanks for this great package, it does exactly what I need!

I'm struggling to make uninstall or reinstall work correctly when the application is still running.
The installer correctly identifies that the application is still running, and offers to "Automatically close and attempt to restart" the application. However this does not appear to actually do anything. My application continues to run and I need to manually exit it.

I'm not sure what this option actually does. Does it fire some event or signal that I need to subscribe to in order to handle?
I've tried subscribing to every node event with process.on() as well as every electron event with app.on() but none of these appear to fire.

What do I need to do in order to successfully close the application when the installer/uninstaller is run?
