Function Dependencies in the Element Selection Tree on Wix

Is there a way to force a specific function to be set if another function is selected in the function selection tree? Is it without the functions being children of their dependencies?

Yes, it should be possible, if you use the Condition element in the Feature element, you can control the level of installation of the function from the condition.

<Feature Id="MyDependentFeature"> <Condition Level="1">(NOT INSTALLED AND &MyMasterFeature=3) OR (INSTALLED AND !MyMasterFeature=3)</Condition> </Feature> <Feature Id="MyMasterFeature"> </Feature>

A few things to explain here:

  • Condition Level="1" tells Wix to set the parent installation level of the installation to 1 (Install) ( Information )
  • (NOT INSTALLED AND &MyMasterFeature=3) If the product is not already installed and the requested action MyMasterFeature is installed
  • (INSTALLED AND !MyMasterFeature=3) If the product is already installed and the installation status of MyMasterFeature is set. ( Information )
