You can download the Bootstrapper Package from:http://www.microsoft.com/downloads/en/details.aspx?FamilyID=5d57c998-b630-4f38-afaa-b79747a3da06&displaylang=en
The bootstrapper package, adds the Microsoft Office 2010 Primary Interop Assemblies to the Prerequisites Dialog Box in Visual Studio 2010 or Visual Studio 2008. Then when you deploy with ClickOnce or Windows Installer, you can select this option to deploy the Microsoft Office 2010 PIAs to end-user computers.
Happy reading!!
