For those who are searching for an answer, this is what has worked for us:
private void PlanPackageBegin(object sender, PlanPackageBeginEventArgs e)
// if this is the package, which has optional features
if (e.PackageId.Equals("<package_ID_with_optfeatures>",
StringComparison.Ordinal))
{
// if the action being planned is Modify
if (this.plannedAction == LaunchAction.Modify)
{
// set the state of the package to present, which will prompt the
call to PlanMsiFeatures
e.State = RequestState.Present;
}
}
and as you can see in the log, it correctly finds that I have 3 features
installed and that I want to remove two of them (and does so quite nicely!
