Sorry but your advice did not work out...tried exactly what you said using a unzip wizard and even just selected extract files to no avail, when starting 1946 it still displays 4.08 on the start up screen. Getting very frustrated now and have tried all the folders from the main ubisoft then 1946....the file appears on the drop down within 1946 but has not loaded into the game...sorry but am I doing something awfully wrong?
