.Net Programmability Support must be selected when installing Microsoft Office if you want to get PIAs installed on the system. Or you need to install a redistributable package yourself. Otherwise, use Visual Studio to install or generate them. You can read more about different ways of installing PIAs on the system in the Office primary interop assemblies article.
