Unable to Properly Uninstall Application after Slipstreaming Patch in Bundle

[KarthikChandran303]

Hi all,
I have a Bundler that includes a "MainInstaller" msi package and a patch (which is slipstreamed) within a Chain like this:

<Chain>
<MsiPackage Id="MainInstaller" SourceFile="$(var.MainInstaller)" bal:DisplayInternalUICondition="WixBundleAction >= 0" Visible="no" Vital="yes" Permanent="no"/>
<MspPackage Id="Patch" SourceFile="$(var.Patch)" Vital="yes" After="MainInstaller" Slipstream="yes" Permanent="no"/>
</Chain>

Uninstalling the bundle only removes the slipstreamed patch. Any ideas as to why the main installer is not being removed?

I am also providing a part of my log which gets generated when I uninstall:

Thanks for the help!

Hi @KarthikChandran303,

I'm having a similar problem. I started looking at migrating my installation code from WiX 3.x to v6.0.0 and have found that WiX 6.0.0 generated bundles only uninstall the patch whereas in WiX 3.x both the MSI and the slipstreamed MSP were uninstalled when the bundle was uninstalled.

Did you ever find a solution to this issue?

Thanks, Darren

Maybe related to this: #7778?

Thanks for your reply and I apologise for the delayed response, but I have been away on annual leave.

In the case of #7778 their problem relates to multiple bundles with mixed versions of WiX Toolset, whereas my problem relates to a single v6.0.1 bundle that contains an msi and an msp that is slipstreamed during installation of the bundle. However, when the bundle is uninstalled only the slipstreamed msp is being uninstalled and the baseline files from the msi remain installed.

The bundle code snippet is something like that below:

<Chain>
<MsiPackage Id="UpdateService_x64.msi" SourceFile="$(var.BaseMsiFolder)UpdateService_x64.msi" />
<MspPackage Id="UpdateService_x64.msp" SourceFile="$(var.CurrMspFolder)UpdateService_x64.msp" Slipstream="yes" />
</Chain>

I would like to move our WiX v3 code over to v6 but this is causing me problems so any help would be greatly appreciated.

Thanks, Darren
