Other languages are also present in FVords, but not so good in their contents and learning modes. The program interface can be chosen between English, Russian and Ukrainian.
The program runs with MS Windows and, with some restrictions, can be used under Linux's Wine.
It is 32-bit and need Windows-1251 charset coding.
FVords installer is available through this link:
You might get an antivirus warning - be not afraid, it's rather standard warning for downloaded '.exe' files.
For details, see a demo sort of documentation available in "Help" menu of FVords.
