WiX Bundle doesn't give upgrade prompt

[Maazaowski]

Question

Hello,

I’m working on a WiX project for my .NET 8 application. The project consists of a WiX MSI installer and a Bundle project that ties together the MSI along with some third-party dependencies, such as Desktop Runtime and ASP.NET.

This WiX setup is a migration from InstallShield, so I need the UI/UX to closely match that of InstallShield. In InstallShield, when performing an upgrade, a pop-up would notify the user that the application is already installed and that this is an upgrade.

I’ve noticed that the same pop-up appears when using the MSI UI in WiX, but when I enable the Bundle UI, the upgrade prompt doesn’t show up.

Is there a way to enable the upgrade prompt in the Bundle UI? The Bundle UI looks more modern, and I’d prefer to use it, but I want to replicate the InstallShield behavior.

This is what the Bundle.wxs look like:

	</BootstrapperApplication>
