Install Office primary interop assemblies

  • Article

Install the Microsoft Office primary interop assemblies (PIAs) when you install Office.

Note

Interested in developing solutions that extend the Office experience across multiple platforms? Check out the new Office Add-ins model. Office Add-ins have a small footprint compared to VSTO Add-ins and solutions, and you can build them by using almost any web programming technology, such as HTML5, JavaScript, CSS3, and XML.

Prerequisite

Ensure that you have a version of the .NET Framework that is no older than 2.0.

To install the PIAs when you install Office

Install Microsoft Office.

Warning

By default, PIA's are embedded in your solution when you build it so you don't have to distribute PIAs to users as a prerequisite to using your VSTO Add-in or customization.
