[wix-users] Bootstrapper - Change

[Ondrej Krc-Jediny]

I have a managed bootstrapper application where I try to implement
Change/Repair/Remove functionality (my .msi support all of them).
I'm having problem with the feature Change functionality. After user
selects/deselect features in my BA, I try to run:

bootstrapApp.Engine.Plan(LaunchAction.Modify);

but the .msi is never run, probably because of 'execute: None' - log:

Planned package: instmsi, state: Present, default requested: Present, ba
requested: Present, execute: None, rollback: None, cache: No, uncache: No,
dependency: Register

As already pointed out in this thread -
http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/How-to-modify-MSI-from-the-custom-bootstrapper-td7585752.html
-

in the PlanPackageBegin event, the RequestState is already Present and
execute ActionState is not modifiable.

It does the same when I try

bootstrapApp.Engine.Plan(LaunchAction.Install);

My MsiPackageElement looks like this

<MsiPackage EnableFeatureSelection="yes" SuppressSignatureVerification="no"
SourceFile="installer.msi" Id="instmsi">
  <MsiProperty Name="ADDLOCAL" Value="[FEATURES]"/>
  <MsiProperty Name="REMOVE" Value="[FEATURES_REMOVE]"/>
  <MsiProperty Name="REINSTALL" Value="[FEATURES_REINSTALL]"/>
</MsiPackage>

For the Change functionality, I fill the ADDLOCAL and REMOVE variables
accordingly.

I don't want to run LaunchAction.Repair, because it re-installs already
installed features (which is not how the .msi Change behaves).

Is there any way to ensure that my .msi is run in such case?
Thank You
