InstallScript

In InstallScript, the function FeatureIsItemSelected returns TRUE if a feature is currently selected in one of the feature-selection dialog boxes (such as SdFeatureTree).

MSI

Windows Installer defines conditions of the form &FeatureName=n, which detect a feature's action state. For example, to determine if a feature called ProgramFiles is selected to be installed locally, and it was not already installed, use the condition &ProgramFiles=3.
