Uninstalling a WiX 6.x bundle that contains an MSI and a slipstreamed MSP only removes the MSP

[ListechAu]

Question

Hello,

I have a single WiX v6.x bundle that contains a WiX 6.x msi and a WiX 6.x msp (minor upgrade) that is slipstreamed during installation of the bundle. The bundle installs okay but when it is uninstalled only the msp is being uninstalled and the baseline files from the msi remain installed.

The bundle code snippet is something like that below:

The above code worked fine in WiX 3.x with both the msi and msp being uninstalled when the bundle was uninstalled.

Is this a problem with WiX 6.x or a change in behaviour that I can work around by modifying my bundle code?

Any help would be greatly appreciated.

Thanks, Darren

Yeah, you'll need to dig into the log file to really understand subtle issues like that.

Hi Rob,

Thanks for your response. This issue really still has me stumped.

I have examined the log files and still can't seem to work out why just the .msp is being uninstalled when the bundle is uninstalled.

Concentrating on just one of the MSI and MSP pairs included in the bundle I have extracted what I believe are the relative sections from the bundle install log:
