vsto - Is Office 2007 PIA deployment possible without Office 2007?

Question

Does Office 2007 PIA also require Office 2007 to be installed? Can I deploy Office 2007 PIA with VSTO 3.0 (without having Office 2007 installed)?

EDIT: I have a windows application that generates MS Word files. I have added the Office 2007 PIA as custom pre-requisite in the setup, but Office 2007 PIA needs MS Office 2007 to be installed.

I just wanted to know that if VSTO does not require Office Installation, then maybe i can convert my application to VSTO.

Answer 1

In order to use VSTO you must have Office Installed. The VSTO PIA's only provide a shim between .NET and the COM interfaces that Office exposes. So the PIA's can do nothing w/o Office.
