Office 2003 Update: Redistributable Primary Interop Assemblies is available for download
This article has been archived. It is offered "as is" and will no longer be updated.
The Microsoft Office 2003 Primary Interop Assemblies (PIAs) redistributable is a Microsoft Windows Installer package that contains the Primary Interop Assemblies for Microsoft Office 2003 products.
These Microsoft Office 2003 PIAs make interoperability easier between managed code and Office 2003 COM-type libraries. Microsoft Component Object Model (COM) interop assemblies allow for unmanaged (COM) code to be called from managed (.NET) code by using the Microsoft .NET Framework and the common language runtime. COM interop assemblies allow for managed applications to bind to unmanaged types at compile time. Then, the application can provide information to the common language runtime about how the unmanaged types must be marshaled at run time.
While any number of COM interop assemblies may exist for a particular type library, only one COM interop assembly is designated as the PIA. The PIA contains the official description of the unmanaged types that are defined by the publisher of those unmanaged types. Additionally, a PIA is always digitally signed by that publisher.
Generally, you must avoid the use of any Office 2003 COM interop assembly that is not provided as part of the Office 2003 PIAs. You must also avoid the use of any Office 2003 COM interop assembly that is generated by Microsoft Visual Studio .NET at design time. Any Office 2003 interop assembly that is not included in the Office 2003 PIAs download is considered unofficial.
