Heroes of Might and Magic III. Complete Collection.

I have the same problem. They suggested using the Key Switcher program as a solution.

Hmm... I'll try it.
By the way, I forgot to mention that my friend has the opposite problem: even in the Russian version of Complete, he can only type in English, and we've tried all the fonts in HD mode, but without success.
Actually, I think it's better to have English fonts than Russian ones, because I can write in Russian using English letters, but with Vietnamese and Romanian, I have problems and have to deal with extra keys.
