conditional installation not working for administrative install wix toolset

I am trying to extract msi using administrative install in order to create patch, but it is not extracting all the components, I suspect this is due to the conditional install element which works fine in regular install

<Feature Id="SomeFeature" Level="0">
        <ComponentGroupRef Id="Somecomponent" />
        <ComponentGroupRef Id="Somecomponents" />
       <Condition Level="1"><![CDATA[(SOMEPROP = "true") OR (REMOVE ~= "ALL")]]></Condition>
      </Feature>

is it possible to use condition element for administrative install? SOMEPROP property value is true by default and is changed on some custom action which i believe wont run in administrative install.

Solution

  • According to the Windows Installer SDK:

    A feature with an installation level of 0 (zero) is not installed during any installation, including administrative installations.

    You need to reverse your logic so that the feature is installed by default and conditionally disabled.
