[wix-users] Burn not performing minor upgrade

[Kevin Mackey]

I'm having a problem where burn is not doing a minor update/upgrade of the
MsiPackage. Burn sets REINSTALLMODE, but not REINSTALL.

I have EnableFeatureSelection="yes", and my managed BA handles the
OnPlanMsiFeature() callback. MajorUpgrade and Repair work.

Here's some of the OnPlanMsiFeature callback code (C#):

private void Bootstrapper_PlanMsiFeature(object sender,
PlanMsiFeatureEventArgs e)
{
    if (e.PackageId == "MyPackage")
    {
        switch (e.FeatureId)
        {
            case "AppFeature":
                if
(this.Bootstrapper.Engine.StringVariables["AppFeatureChecked"] == "True")
                {
                    e.State = FeatureState.Local;
                }
        . . .
        }
    . . .
    }
. . .
}

Here's some of the bundle log, with product identifications replaced with
"MyPackage" and "AppFeature":

MSI Log:

MSI (s) (74:48) [16:01:41:228]: Command Line: ARPSYSTEMCOMPONENT=1
MSIFASTINSTALL=7 INSTDIR=C:\Program Files\MyCompany\ REINSTALLMODE=vomus

Notice that REINSTALLMODE is set, but not REINSTALL. When I repair,
REINSTALL has the list of features, which I expect to be the same when
doing a minor upgrade.
