Installing : Installing System Architect : Installing System Architect : Setting the local language
  
Setting the local language
To override the default setting for language support during installation, use the File_Lang option.
If System Architect is installed on a version of Windows running one of these languages, it sets up the product in the system language.
For example, to install System Architect in Spanish, use:
ratlSysArch_11-4.exe /v"FILE_LANG=\"3082\""
This parameter can also be used as part of a silent install. The installer itself is displayed in the language of the operating system: FILE_LANG does not affect it. In the example above, if you install Spanish on an English version of Windows, the installer dialogs are in English: however, the installed version of System Architect will be in Spanish.
