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.

Enterprise Architect System Requirements

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


Installation on Linux

If you intend to run Enterprise Architect on Linux, refer to the page Installing Enterprise Architect inside Wine, 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

You also 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
