MKV muxer window can't be used if a first error occurs
Yes, now it's works. Thank you for your correction ! There is a bad translation here : "After encoding" is translated in french by "Lors du codage". The translation must be "Après l'encodage".
I try the switching : I switch to Spanish and to English : it works (menu, settings and GUI in english). But when I close and relaunch the application : I have the same problem : menu is in english, settings are in english, but GUI (main interface) is in french.
But are you french or american ? Because I thing the problem depend of the default Windows language. I will reinstall it for check.
English language not working
