System Requirements

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

Enterprise Architect System Requirements

Windows Vista / Windows 7

Under Windows Vista and Windows 7 (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 or Windows 7, 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.

Install Local Help

When you select to display Help in Enterprise Architect, by default it opens the appropriate topic in the Help on the Sparx Systems website. You can, however, download the EAUserGuide.msi file from the 'Resources' page of the website, to install the HTML Help files on your local machine so that you can display Help information without accessing the Internet.

EA should be restarted after installing the local HTML Help files.

Installation on Linux and MacOS

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.

Under Linux, Formatted Notes text on diagrams might not display correctly.

Installation inside Wine

Using a Third Party DBMS as Model Repository

If you plan to use SQL Server, MySQL, PostgreSQL, Access 2007, Sybase Adaptive Server Anywhere or Oracle 9i, 10g, 11g or 12c as a model repository, then you must use the Corporate, Business and Software Engineering, Systems Engineering or Ultimate editions of Enterprise Architect.

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.

Users planning to use SQL Server, MySQL, PostgreSQL, Sybase Adaptive Server Anywhere, Access 2007 or Oracle 9i, 10g, 11g or 12c as their model repository can access scripts that create the required data structures for the choice of DBMS, from the Sparx Systems website.
