System Architect supports the following languages: Chinese (Simplified), Chinese (Traditional), Czech, English, French, German, Japanese, Korean, Portuguese (Brazilian), Russian, and Spanish.

When System Architect is installed on a version of Windows running one of the supported languages, the product is installed in that language. To override the default, use the FILE_LANG command. For example, you can install English on a German version of Windows, by using the command and specifying the country code for German.
