... the UbiSoft version of the game includes the TELP 1.3 patch fixes and will run reliably on Windows 10, but it's only available in English. This 'patch' is a file swap that replaces the English text and voices with those in French. This process creates the French localization that's missing from UbiSoft.
And I would remiss if I didn't mention that this effort would not have been possible without the interest and action of Dorade, a French fan who brought this shortcoming and its fix to our attention. Thanks, Dorade!
