Hi

This depends on which PIA you are using.

For Office XP, you can look into the link below we can including the PIA in
a VS,NET setup project.

Distributing Solutions That Rely On the Office XP PIAs
You have several options to distribute a Visual Studio .NET solution that
relies on one or more of the Office XP PIAs:

Have the end user of your solution manually install the required Office XP
PIAs on their computer before running your solution. This option is only
recommended for technically advanced end users. See the Installing the
Office XP PIAs section above for details.
Place the required Office XP PIAs in the same directory as your solution
and distribute your solution and the Office XP PIAs as a single unit. This
option is only recommended for simple solution deployments, such as copying
solutions from one file directory folder to another across a computer
network. The main disadvantage with this option is that multiple copies of
the same Office XP PIAs may be installed on end users' computers, which
reduces these computers' available hard disk space.
Install the required Office XP PIAs on end users' computers through the use
of a Visual Studio .NET Setup project. This option is recommended for most
deployments as it automatically installs and registers the required Office
XP PIAs, as well as reduces the number of duplicate Office XP PIAs on end
users' computers.

While for Office 2003 PIA, it has no standalone package, we must install it
with office 2003 installation program, that is to say it can not be
redistribute with our setup project.
We can add a readme file to request the end-user to install it with office
2003 installation program.
