The present invention discloses a software program that includes a first set of one or more compressed files and an executable file. The executable file can include a second set of one or more compressed files. The software program can be a self-executing program stored in a machine readable medium. Executing the software program can result in an automatic extraction of files contained within the first set and the second set of compressed files. In one embodiment, the software program can be an installation program, which includes a configuration file specifying settings to be applied during an installation process. The installation program can be dynamically constructed at a time an installation file is requested. The installation program can be a network lean file containing only those necessary components for a customized installation, which minimizes an amount of time and bandwidth expended when transferring the installation program over a network.
