[wix-users] Overriding current state of an msi package in custom bootstrapper

[Hoover, Jacob]

Are these 3 applications mutually exclusive or is it a user preference as to which ones they want installed?  Also, you didn't define how they got 1.0.0.51, so I am not certain if this is a self-updating application (in which case the users selection of A1 should still remain).

Subject: [wix-users] Overriding current state of an msi package in custom bootstrapper

We have a bootstrapper bundle which chains 3 individual application msi. Bootstrapper custom UI allows user to choose which application to install And based on the selection custom bootstrapper will install its msi.

Now consider the scenario.
Application, say A1 version 1.0.0.50 is installed in the system. Assume bootstrapper version is also 1.0.0.50

Assume next version of bootstrapper installer with some updates is available, Assume its version is 1.0.0.51.

My requirement is I should be able to uninstal A1 using the installer version 1.0.0.51.
But this latest installer does not detect the msi package current state as present.
here is excerpt from the log:
Detected related package: {92482FD1-38EE-474E-B4C0-32C8FBDF9C0B}, scope: PerMachine, version: 1.1.0.329, language: 0 operation: MajorUpgrade
[29F0:04E0][2016-08-26T10:50:11]i000: In OnDetectRelatedMsiPackage  event parameters are : CCAdmin and result is None Detected package: CCAdmin, state: Absent, cached: None

[29F0:04E0][2016-08-26T10:50:22]i201: Planned package: CCAdmin, state: Absent, default requested: Absent, ba requested: Absent, execute: None, rollback: None, cache: No, uncache: No, dependency: Unregister

Is it possible to override the current state of this msi package programatically?

My intention is to set Current State as Present, BA reques state as absent so that Bootstrapper engine will uninstall this package when I invoke Engine.Apply()
