I install play in french language,
but i experienced some probable error in the name of the region, particulary for the naval raiding events (exemple: Ostasien fleet raid in a region near Nantes, when Saigon is closer) or some loss of NM event with a "." or "2%" when it should be a place.
So maybe this mistake doesn't exist in english...
So how to convert the game in english?
(i understand it better than i spell it )
