Hi

Thanks for your quick reply.
According to the Readme shipped with the package, we have the following
choice.
Installation
To install the Office 2003 Primary Interop Assemblies, follow one of the
following methods:
1 Double-click the O2003PIA.msi file
2 Execute "msiexec.exe /i O2003pia.msi", or
3 Wrap the O2003pia.msi in another setup package through Visual Studio or
other Windows Installer aware setup editor.

Please note that the Office 2003 Primary Interop Assemblies setup does not
support the /a or /j options for MsiExec.

For third option, I think you may try to take a look at the link below.

Also we have specified queue about setup project, if you still have any
concern ,please feel free to post there, so that experienced expert will
give you more idea.
microsoft.public.platformsdk.msi
or
microsoft.public.vstudio.setup
