The ProductLanguage property specifies the language the installer should use for any strings in the user interface that are not authored into the database. This property must be a numeric language identifier (LANGID). If a transform changes the language of the user interface in the database, then it should also change the value of this property to reflect the new language.
This property is REQUIRED.
The value of the ProductLanguage property must be one of the languages listed in the Template Summary property.
When authoring a package as language-neutral, set the ProductLanguage property to 0 and use the MS Shell Dlg font as the text style for all authored dialogs. Because some fonts do not support all the character sets, by using this font you can ensure that the text is correctly displayed on all localized versions of the operating system.
