ClawsMail - Change language?

Well, when installing, I selected English language.
It basically ignored the setting and shows me Russian interface inside mail client.
Where can I change it in preferences? I do not see any option for that

A fast followup and a robust solution: delete “C:\Program Files (x86)\GNU\GnuPG\share\locale\ru” folder, after that the program forgets that language language and shows all interface in english.
To Devs: Sorry guys, you suck. Not as programmers but as developers. Or did you port it just to kick some windows users in their balls?
