Upgrade Agent is a software and system component upgrading and registering tool. Upgrade Agent compares source and target files versions and language supported attributes, sizes and dates, and then upgrades target files if different from, or newer than the source. Upgrade Agent execution may be scheduled, so upgrading, maintaining, keeping up-to-date and registering software or system components can be done on many computers from a centralized location. It exists as a command line tool, an interactive graphical tool and a service. Upgrades may be fully automated and scheduled under NT using this service\; under Windows, you may use a Windows scheduler, the login script, the startup folder or the "run&quot\; key in registry. The graphical part of this tool may be used to produce, print or export a complete report describing copy operations made, and file attributes.
