WiX v5 base setup uninstall with Hotfixes (RTM + HF1 + HF2 and then uninstall RTM)

[yuvnith]

Question

Scenario:
I have installed the following in sequence: (all 3 setups are generated using WiX v5)
RTM
Hotfix 1 (HF1)
Hotfix 2 (HF2)

Now, when I try to uninstall RTM, I observe the following behavior:
HF1 uninstall is triggered before HF2, even though HF2 was installed last.

Impact:

We have a validation that checks whether a lower version setup is being uninstalled while a higher version is still present. This behavior violates that check and causes issues in our uninstall

Request:
Can anyone help me understand why HF1 is being uninstalled before HF2, and how to resolve or work around this issue to ensure proper uninstall sequencing?

Hmm, I'm not sure the order of related bundles' execution has ever been guaranteed.

Is there any way to make sure that the newly installed Hotfix/patch gets uninstalled first ?

It worked fine with WiX v3, we observed this issue only after we migrated our setups to use WiX v5

@robmen and @yuvnith ,
I'm encountering the same issue.

When attempting to uninstall the base setup, Patch1 is removed before Patch2, which is not the expected behavior.

In WiX v3, this issue did not occur. However, I'm seeing this behavior in WiX v5.

@robmen ,
Is there a way to control the uninstall order so that the latest patch (e.g., Patch2) is uninstalled first, followed by the earlier patch versions?

I'm not sure. There were a bunch of bug fixes in WiX v4 in Burn that could have introduced new behavior. I didn't work on that area myself so it's not top of mind for me. You'd want to start by looking at changes in src\burn\engine that's where all the code lives.
