[wix-users] How can I control what an added Change button in my bootstrapper’s Modify Setup does?

[Sean Hall]

It's not clear what you're asking for. If you want the bundle to show the
MSI UI during anything besides the initial install, then that's not
supported in v3. You would have to get the bundle to show its own UI. That
would require writing your own custom bootstrapper application.
