Description
If you intend to distribute the latest version of your installation as a small update or a minor upgrade, you must follow certain rules if you decide to add features to the installation. The first rule is that the feature must be added as a child to an existing feature. The second rule is that the feature must have its Remote Installation property set to FavorParent and its Required property set to Yes.
If these two rules are not followed, the contents of the new feature will not be installed when the upgrade is applied. Instead, the end user will need to run the installation in maintenance mode and manually select the feature to be installed locally.
This validator does not apply to major upgrades.
To perform this validation test, the validation engine compares the latest installation to an earlier version of that installation.
Corrective Action
Add the new feature as a child of an existing feature, and set its Remote Installation property set to FavorParent and its Required property set to Yes.
