Abstract: Identifying program module functionality needed by a computer when disconnected from a network is disclosed. A document identification engine (DIE) creates a list of files stored locally on the computer. The DIE sends the list of files to a document mapping engine (DME). The DME identifies a proper handler routine for each file in the list of files and sends each file to the proper handler routine(s). The handler routine(s) identifies the application functionality needed to execute each file. The application functionality may include products, features and components. The handler routine sendsd a list of needed application functionality to the DME. If needed, the DME may send any sub-parts of files to another handler for further processing, such as when a word processing document includes a spreadsheet subpart. The DME also can send the list of needed application functionality to a migration engine (ME). The ME determines the current status of the needed application functionality.

Abstract: Dynamically creating or modifying an install-set of a program module comprising required components and optional components. Usage and configuration parameters are detected in the operating environment of the target computer system. Usage parameters relate to past usage of prior versions of the components of the program module. Configuration parameters may be any configuration aspect of the operating environment, including hardware and software configuration. Based on detected usage and/or configuration parameters, determinations may be made as to whether each of the components of the program module are to be included in, or excluded from, an install-set. The install-set is the set of required and/or optional components that are selected for installation onto the target computer system. Based on the determinations, the install preferences of each component are set. Install preferences are properties that signal whether each component is to be installed by an installer module.
