Changing Language for non-Unicode Programs
Also known as "System Locale" in Windows 2000. This setting enables programs that do not support Unicode to display menus and dialog boxes in their native language by installing the necessary code pages and fonts. However, programs designed for other languages may not display text correctly.
To perform this procedure, you must be a member of the Administrators group on the local computer, or you must have been delegated the appropriate authority. If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure.
Only non-Unicode programs are affected by this setting. The language you select for this option does not change the menus and dialog boxes of Windows or other Unicode programs.
Follow steps 1 - 4 from "Add Language Support" above.
Click on the "Advanced" tab
Under "Language for non-Unicode program," select the language version of non-Unicode programs that will be used.
Follow the on-screen instructions. You will be prompted to reboot the system. Click Yes to complete the change.
