Register a Full License

The free Trial Edition 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 Enterprise Architect Edition (Professional, Corporate, Unified or Ultimate) is activated after installation.

The Corporate, Unified 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.
