The feature and component states are not valid until the CostFinalize
action is run. However, if you want to check that features for your
application are installed, you can shadow the installation state with
a registry value. The registry value is in a component that belongs
only to the one feature. If the feature is installed, the registry
value is written. You can then use AppSearch to scrape that out
during a modify, repair, patch, or uninstall scenario.
