[wix-users] Convincing internal MSI to run during Modify mode with custom bootstrapper

Wed Oct 23 11:58:53 PDT 2019

I got this idea to work by setting a variable.  I am still not sure why it did not work using the feature name, but at least I seem to have something that works now.  I will circle back to this again later.  I assume my original condition is just incorrect, but I have other fish to fry at this time.

Thanks for the suggestions.

This code correctly installes/uninstalls the feature.
    <Feature Id="FeatureChange" Title="Feature To Force Change Mode" Level="0">
      <Condition Level="1"><![CDATA[(ENABLE_FEATURE_CHANGE = "1")]]></Condition>
    </Feature>

So I assume the XML snippet bellow looks correct then?  At least at first glance.  Maybe a feature must have a least one component otherwise it does not get installed?

I will look into running the MSI directly.

Have you attempted to property drive the MSI from the command line to isolate if this is an MSI authoring error or a custom BA error?

Yep, which means that my code bellow should work.  That's why I am confused.  I want it to install FeatureB if it's not installed and I am asking it to install.

>From that site:
For example, the conditional expression "&MyFeature=3" evaluates to True only if MyFeature is changing from its current state to the state of being installed on the local computer, INSTALLSTATE_LOCAL.

I have done a lot of reading and think I have a better grasp on how WiX/MSI process things.  I am still having an issue though, probably with my syntax.  Hope you can help.

In my bootstrapper log file it shows that the two features (One conditional, the other not) are planned to be installed (AddLocal).  In the MSI log file however it seems the condition on FeatureB was not evaluated as true, so that Request and Action is set to Null.  Seeing as I set the planned state for FeatureB to Local, who does (&FeatureB = 3) evaluate to false?

    [09A8:4B80][2019-10-14T08:23:45]i203: Planned feature: FeatureB, state: Absent, default requested: Unknown, ba requested: Local, execute action: AddLocal, rollback action: Remove
    [09A8:4B80][2019-10-14T08:23:45]i203: Planned feature: FeatureA, state: Absent, default requested: Unknown, ba requested: Local, execute action: AddLocal, rollback action: Remove

    MSI (s) (50:40) [08:23:59:166]: Feature: FeatureB; Installed: Absent;   Request: Null;   Action: Null
    MSI (s) (50:40) [08:23:59:166]: Feature: FeatureA; Installed: Absent;   Request: Local;   Action: Local

    <Feature Id="FeatureA" Title="Feature A" Level="1">
      <ComponentGroupRef Id="SomeId" />
    </Feature>
    <Feature Id="FeatureB" Title="Feature B" Level="0">
      <Condition Level="1"><![CDATA[(&FeatureB = 3)]]></Condition>
    </Feature>
