ProductLanguage
This variable contains the language ID for the installer's user interface, in decimal notation. The language IDs are defined as per Win32 conventions; see
Language Identifiers on the MSDN web site.
Usage
Used internally by the all installers. You can refer to it as <ProductLanguage>. Do not set this variable manually; it is set by InstallMate when the installation package is built. For multilingual installation packages, this variable is set to 0. Once the user has selected the desired installation language early in the installation process, the variable is updated to the actual language.
