Software fix packs and/or APAR's are maintained at a server for use on a requesting computer system. The requesting computer system makes a request for a specific APAR, which is identified by a version number, from the server. The server determines, by examining the requesting computer's request, whether the requesting computer system has all required software dependencies for the requested APAR. When it is determined what the requesting computer systems needs, the server bundles the requested APAR and any required software dependencies, not already on the requesting computer system, for shipment to the requesting computer system.
