Works great, tried with both English & French, thanks Vovsoft & SoS !
Note, there are 3 flaws if you ask me :
– during install, there is no choice about the install location, goes by default to /program files/(x86)/vovsoft ;
– after install, there is no shortcut made on the dektop ;
– if you resize the main window, the next time you launch it again, it goes back to the default size.
