[wix-users] PackageGroup tries to run both ExePackages on uninstall

DetectCondition should be it. Log file should show decision making.

Subject: [wix-users] PackageGroup tries to run both ExePackages on uninstall

Hi

I'm trying to author a package that performs new installations and also upgrade existing installations.

My bundle includes a 3rd party installer (referred to in the code below as "an_installer.exe").
The 3rd party installer has different cmd line parameters that must be specified when upgrading, and must not be used for new installations.

New installations are working as expected:
1) the "new_customer" PackageGroup runs.
2) the "existing_customer" PackageGroup does not run.

Upgrades are working as expected:
1) the "new_customer" PackageGroup does not run.
2) the "existing_customer" PackageGroup runs.

However, after upgrading, when you uninstall, BOTH PackageGroup are scheduled for uninstall
1) the "new_customer" PackageGroup runs, then
2) the "existing_customer" PackageGroup runs and throws an error.

I'm not sure how to author the code so that only one PackageGroup executes during uninstall.
I don't mind which one executes on uninstall, as long as exactly one does.


Does anyone have any insight into how to do this correctly?
