A server computer (102) in a communication system (100) provides updated software programs to client computers (102) independent of the type of client (104) and the type of server (102). A polymorphic master object (300) has a predetermined structure known to all servers (102) and clients (104). Upon connection of the client (104) to the server (102), the server (102) provides the master object (300) to the client (104). The polymorphic master object (300) includes fields that indicate polymorphic package files that are available for transfer to the client (104). One such field is a distributed install file that includes, in a text format, instructions for instantiating the selected package file. Upon receipt, either the user or the client selects package file. The client (104) provides a request to the server (102) for the selected file, which the server (102) provides to the client (104). Using the distributed install file, the client (104) instantiates the selected package file.
