Windows Installer Question

I use the Microsoft Windows Installer 1.1 to generate a instalation pack of my aplication but i need, before the instalation, run a VB program that loads the table definition in the database.

There are any option to run this program automaticaly in the instalation pack whith the windows installer?

I suggest you learn just a tiny little bit Delphi. It creates standalone .exe applications, so you can create intallation programs using it.
