AppLocale works with many, but not all non-Unicode applications, and as such is still inferior to really setting the particular locale systemwide. In particular, it requires fonts for the particular locale to be installed on the system it runs on, and Administrator privileges to be installed (though not to be used). It is not officially supported for use with Windows Vista or Windows 7; a person who is using Vista or 7 must either alter the system locale manually, or use an available unofficial workaround to install the AppLocale utility (see below).
