How to: Install Office Primary Interop Assemblies

You must install the Microsoft Office primary interop assemblies (PIAs) in the global assembly cache of your development computer before you can perform certain development tasks. Typically, the PIAs are installed automatically when you install Office on the development computer. However, in some cases you might need to install the PIAs separately. For more information, see Configuring a Computer to Develop Office Solutions and Office Primary Interop Assemblies.

You can install the complete set of PIAs in the global assembly cache in two ways:

  • Install them when you install Office.

  • Install them from the redistributable PIA package.

Note Note

You must be an administrator on the development computer to install the .NET Framework and the Office PIAs.

To install the PIAs when you install Office

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

  2. Install Microsoft Office and make sure that the .NET Programmability Support feature is selected for the applications you want to extend (this feature is included in the default installation).

To install the PIAs by using the redistributable package

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

  2. Download the PIAs for Office 2010 from the following page on the Microsoft website: Microsoft Office 2010: Primary Interop Assemblies Redistributable.

  3. Install the PIAs by following the instructions on the download page.
