Configuration user interfaces are dynamically generated in different installation scenarios independently of the application logic being configured. Page definition files specify control properties. Description fragments, extracted from the page definition files, are merged at run time with page templates selected to match the interface type of the target computer. A user interface page is generated on the target computer user interface using one of a plurality of display engines appropriate for the target computer user interface type. User interface generation may be part of a wizard which passes user input to application logic for validation.
