The only downloadable version (GOG or Impulse) is the remastered version. Unfortunately Larian has said that it was only released in English due to time constraints. Perhaps if there is enough demand they may be able to find a French publisher/distributor to do the localization, but until and if that happens you are stuck with trying to find a CD/DVD version (the English disk version is still available via eBay and other places online; the French version may be harder to find).
