That's not really relevant. Since the OS is in Russian, as I've said in my previous message, there are many possible additional problems we might not be aware of, that we don't have any way to test.
I'm sorry but, other than offering Trial versions for all our products, so you can verify on your own system if they work, before purchasing, there's not much we can do to support users with all different OS versions and languages. Some locales have specific issues that usually don't happen on Western-language OS versions so, there might be a solution for your specific issue, but we don't know it and we can't test it.
