Abstract

A technique for the remote installation of application software from a source computer system to one or more target computer systems (workstation) coupled to a Local Area Network (LAN). The present invention allows a LAN Administrator to install application software on a user'"'"'s workstation automatically at any time without user'"'"'s intervention. The state of (i.e. a snapshot of) the LAN Administrator'"'"'s system before and after the installation of the application software is captured and an installation package is built. Installation on the user workstations is then scheduled. For installation, the installation package is transmitted to the user workstation where an install program carries out commands in the installation package for installing the application software.
