Register a Full License

The Trial version of Enterprise Architect available for download is an evaluation version only. For the full version you must first purchase one or more licenses.

The license key supplied determines which edition (Enterprise Architect Desktop, Professional, Corporate, Business and Software Engineering, System Engineering or Ultimate) is activated after installation.

The Corporate, Business and Software Engineering, System Engineering and Ultimate editions can be activated by either a private license key or a shared (floating) license key. Shared license keys, for a user population that includes temporary users, are checked out of and in to a Sparx Systems key store.
