I don't think it's a matter of registry keys. What version of wine do you use ? The latest is wine-1.1.33. Your ~/.wine is maybe corrupted or misconfigured. So "rm -Rf ~/.wine" or move it elsewhere ("mv ~/.wine ~/.wine_backup") and then do "winecfg" to recreate ~/.wine directory. Do Code: LANG=ru_RU man man quit (press q) then Code: LANG=C man man and quit As you can see, it allows you to change the language once (for an application) without overwriting system wide preferences. Can you write and read Russian texts ? If not, it seems you don't have right fonts installed. How did you installed TrueType ? From a package ? Code: err:shell:SHGetFolderPathAndSubDirW Failed to create directory L"C:\\users\\alexey\\\041c\043e\0438 \0434\043e\043a\0443\043c\0435\043d\0442\044b". Do you have enough rights ?
