If you have the English version of the game, the file should be there. Check the folder for any files just named 'config'. Starting with XP, MS' default option in Explorer is to hide file extensions for known file types (you can change this in the Options). There should be two such files in the run folder, config.div and config.lcl (if the extensions are hidden, the file type should differentiate them if the folder view is set to details).
AFAIK the North American and UK releases were identical (my CDs contain the same 'art' number, except they end in 'US2' rather than 'UK2').
