Supported database products (DBMS) for use as an Enterprise Architect model repository
Windows Vista and Windows 7 users
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 recommends that if you are installing on Windows Vista, always run the Enterprise Architect installer with Administrator privileges (recommended whether you have UAC turned on or not). To grant the application Administrator privileges, right-click on the downloaded installer icon and select the Run as administrator menu option.
Supports 32 / 64 Bit processors
 Enterprise Architect is available as either a 32 or 64 bit application, the 32 bit application can be run on both 32-bit and 64-bit Windows Operating Systems, however the 64 bit application can only run on 64-bit Windows Operating Systems.
Linux Version Compatability
 Wine is continually updated. The versions listed here represent what Sparx Systems tested against for the current release. For the best experience, we recommend maintaining an updated version of either the Stable or Development version from winehq.org. Both versions are regularly updated with fixes that will directly improve Enterprise Architect compatibility, but may experience small problems on occasion. In general, we believe that the development version offers the best experience with Enterprise Architect.
Exceptions in Apple OS.
 Apple dropped support for 32 bit applications in macOS 10.15. Crossover will still allow Enterprise Architect to run, but Wine will not.
Databases / EA Editions Support
 The file based databases, MS Jet and Firebird, can be used with any edition of Enterprise Architect. These repository files are named as *.eap and *.feap, respectively. Hosting a model in a server based DBMS repository, however, requires Corporate edition, or higher. For a list of supported DBMS versions see the Help topic Server Based Repositories, under the subheading DBMS Products you can use.
