Dependency Checking

The installer does extensive checking of components to verify that the installation components you select function properly together. Many components have dependencies on other components. For this reason, when you select a component to install, the installer automatically includes the components and subcomponents upon which the selected component has dependencies. You cannot deselect a component if another selected component depends upon that component locally. However, if the dependency is not local, you receive a warning but can proceed under the assumption that the dependency is satisfied by a component on a different host computer.
