The Language in Which the Installer and Configuration Wizard Run

When you launch the Siebel Enterprise Server installer or the Siebel Software Configuration Wizard, it launches in the appropriate language for the locale of your operating system, if this language and locale are supported by Siebel Systems. For this reason, make sure the language setting under the regional option of your operating system is set to the desired choice of your language. If the current locale is not supported, then, when you launch the installer or Configuration Wizard, you are prompted for the language in which to install or configure.
