An application Runtime Expert (ARE) manages deployment of application software on multiple computer systems. The ARE assists the user in verifying and fixing configuration and environment details of an application deployed on multiple computer systems. The ARE creates a user configurable XML template that contains configuration and environment details based on information collected from a master system that has a known good deployment. The ARE allows a user to edit the XML logic in the template and add plug-ins to the template. The XML template with the added plug-ins are sent to a target system and used to verify the deployment on the target system compared to the master system and to make fixes to the target system's configuration.
