How to set à different language?

Hi all,
i unsuccessfully spent many hours on the app and then on this forum, looking for a way to set the app with a different language.
(french)
I found different files in "language" and "translation" folders, in the installation folder, but I don't know how to use it.
Anyone can help me please?

The app should pick the right translation depending on your system preferences.

But try this, delete all the files in YACReader/languages but the french ones, yacreader_fr.qm and yacreaderlibrary_fr.qm

It happens to me too. The entire application is displayed in English except 'About' and 'Help'.
I use Windows 10 and YAC version 9.8.2.2106204

The system language is Spanish. I have tried what you say about deleting the language files, except the *_es.qm but it remains the same.
In fact it does many versions that happens, but with the portable version (6.5.3) it goes well. (I miss the portable version www.yacreader.com/media/kunena/emoticons/crying.png )

A mí también me pasa. Toda la aplicación se muestra en inglés excepto 'About' y "Help".
Uso Windows 10 y la versión de YAC 9.8.2.2106204
El idioma de sistema es Español.
He probado lo que comentas de borrar los ficheros de idioma, excepto los *_es.qm pero sigue igual.
De hecho hace muchas versiones que ocurre, pero con la versión portable (6.5.3) va bien. (Echo de menos la versión portable)

I will take a look, maybe there is something wrong with the code.

For your information: Same problem here with the german language.

I'll add some settings to control how language is chosen.

for yr info the issue is the same with the italian language......pls try a fix.......thxs so much indeed cheers
