Abstract

A method and system for installing software on a computer prepares a computer system for the installation of a suite having a plurality of components. A setup program queries each component to determine which of the components is a prerequisite to the installation of the suite and which is a prerequisite for installation in a particular scenario. The setup program installs those components that are determined to be suite or scenario prerequisites on the computer system. The setup program creates a baseline installation image containing the installed components as well as the data elements required to complete the installation of the suite.
