Enterprise Architect is distributed as a single executable setup file (.exe). After you execute this file, Enterprise Architect is immediately available to create projects as .EAP files.

If you plan to use the Corporate, Business and Software Engineering, Systems Engineering or Ultimate edition with SQL Server, MySQL, PostgreSQL, Access 2007, Sybase Adaptive Server Anywhere or Oracle 9i, 10g or 11g as a model repository (see below), you require additional files and supplementary installation processes. Please note that installation and maintenance of these database management systems is not covered under the support agreement.

The latest evaluation and registered versions of Enterprise Architect are always available from the Sparx Systems website. The registered version is available through the registered user area of the web site, which requires a username and password to access. These are provided upon purchase of a license.

System Requirements

The system requirements for installing Enterprise Architect are defined on the Enterprise Architect | System Requirements page of the Sparx Systems website.

Windows Vista

Under Windows Vista (with User Account Control turned on) an application starts with only Standard permissions, regardless of what level of authority the current user has. As a result, an installer run normally with an Admin account under Vista only has Standard privileges and either is not able to write to certain critical areas of the registry/file system, or redirects the write requests to a per-user virtualized registry/file system.

Sparx Systems recommend that if you are installing on Windows Vista, always run the Enterprise Architect installer with Administrator privileges (right-click on the downloaded installer icon and select the Run as administrator menu option).

Install Enterprise Architect

Run the Enterprise Architect setup program. Generally you can accept all the default options without change.

To place Enterprise Architect in a directory other than the default, enter the name of the destination when prompted.

You might be prompted to restart your computer when the installation completes. Although this is not always necessary (if you already have the components Enterprise Architect requires installed on your computer), you should restart just to be certain.

If you intend to run Enterprise Architect on Linux, refer to the Installation and Use page on the Sparx Systems website. To support the Scripting facility in the Corporate and extended editions of Enterprise Architect, you must also install Internet Explorer 6.0 or later revisions.

Corporate, Business and Software Engineering, Systems Engineering and Ultimate edition users planning to use SQL Server, MySQL, PostgreSQL, Sybase Adaptive Server Anywhere, Access 2007 or Oracle 9i, 10g or 11g as their model repository can access scripts that create the required data structures for the choice of DBMS. You can find these at one of the following pages:


Enterprise Architect requires Read/Write access to the program files directory where Enterprise Architect has been installed.
