A system, method and device for installation and/or deinstallation of at least one software module, with centralized resolution of constraints, in aircraft equipment items. After having received a list of software module references, the list comprising at least one reference to the at least one software module, and at least one command, linked to the at least one reference, for installation of deinstallation of the at least one software module, the constraints are accessed. This access is independent of the access to the at least one software module. A sequence of basic operations resolving the constraints then is evaluated for applying the at least one command to the at least one reference.
