In a method of delivering software over a network a server presents a software feature selection list to a client. In response to selection of selected features from the software feature selection list, the server determines a set of software modules required to perform the selected features. The set of software modules includes a subset of core modules and a subset of non-core modules. The server begins downloading to the client machine the set of software modules. The client stores the core modules in core module storage as they are received. The client stores the non-core modules in non-core module storage as they are received. While the client is receiving and storing downloaded modules, the client determines if it has received the subset of core modules. The client examines a core module from the core module storage. If the client has installed all prerequisite modules for the examined core module, the client machine installs the examined core module; otherwise, the client examines another core module in the core module storage. The client continues to examine and install core modules until all of the core modules have been installed. After installing all of core modules, the client examines a non-core module from the non-core module storage. If the client has installed all prerequisite modules for the examined non-core module have been installed, the client installs the examined non-core module; otherwise, the client examines another non-core module to the non-core module storage. The client machine continues to examine and install non-core modules until all of the non-core modules have been installed.
