To install additional components after installation is complete, run the installer again to add them. The installer detects installed components and uses them to satisfy dependencies of components you are adding. Installed product components are shown as shaded and dimmed on the Choose Software Components page. For example, if you installed Access Manager and its required components during one installation session and later decide you want to install Portal Server, the existing instance of Access Manager is used to meet the Portal Server dependency on Access Manager. You are not asked to reinstall Access Manager.
