just looked in data1.cab, you need to add to instructions, to move unins000.* files before starting compression, replace afterwards ( to uninstall original version )
also step 4
4. Go to game folder\audio\soundbanks\speech and delete all languages except your one (if neccesary)
is NOT needed as there is only 3 files no matter which version you install. ( tried en,fr,de same for each one only 3 files )
