Your new Bundle can carry an upgrade of the MSI but your Bundle definitely needs to support silent operations to upgrade correctly.

Subject: [wix-users] Upgrade using Burn with Custom BA

Hi everyone,
I'm trying to upgrade my app that was previously installed using custom BA that chained prerequisites and the app's msi.
Doesn't matter whether I try doing a minor upgrade (changing only version number) or major upgrade (changing version number and also product Id), The new BA calls the old one with -uninstall -silent.
Why is that?
My old BA doesn't support silent uninstall? Is there a way around that? Can I just uninstall the msi? Or perhaps do a minor upgrade that doesn't try to uninstall the BA?

Thanks in advance,
Roni (Aron) Fuchs
