Show installation progress + success/failure in installation step 5
Motivation
The installation dialog disappears, so the actual installation feel a bit disconnected. I got the following (typical) messages with Move Hub, but it isn't super intuitive where they come from, or how to deal with them.

Suggestion
Something like shown below. The buttons at the bottom would be disabled at first.
- "Install again" just takes you back to previous step.
- "Done" closes the dialog
Since it would probably be hard to show the errors here as well, it's probably fine if they remain popups at the stop. If the dialog is open like this, they can easily click "install again" if errors occur.

I'm not opposed tot the idea. And I already spend half of a day trying to implement it. But I found it to be way too technically complex given the available toolkit and I didn't get anywhere near a decent UX in that time. So I came to the conclusion that the current implementation is "good enough" and our time is probably better spent on something else.
