The installer sets this variable to the default language ID for the current user, in decimal notation. The language IDs are defined as per Win32 conventions; see External link Language Identifiers on the MSDN web site.


Used internally by the installer. You can refer to it as <UserLanguageID>. Do not set this variable manually; it is set by all installers during installation.
