Abstract: A system and method for achieving unitary installation of software at each time software is installed in user units of a distributed computer system. A specially adapted recipe is created from a general recipe which has fewer questions than the general recipe, or even no questions at all. This requires less information, or no information, from the user. This specially adapted recipe may either be used to achieve unitary installation of a program product in a plurality of mutually similar units of a computer system. The method enables a specially adapted installation recipe or configuration recipe to be created which can be re-used for manually, semi-automatically or fully automatically creating, installing or reconfiguring software. This reduces the total work in creating and/or installing a plurality of software programs or reconfiguring existing software while being aware of how these were created and/or installed or configured.
