Installing HotA on the Astra Smolensk Linux operating system.

Are you serious? Is that OS used at your workplace or in the military? It's unlikely that you installed it on your home PC (although it's possible). In general, you can install Wine on Linux and use it to install various Windows programs. Or, you can install an emulator (VirtualBox) and install Windows in it, then install "Heroes" and HotA in that Windows environment. Last year, I tried several Linux distributions (from the Debian family) at home; some of them were good, but "Heroes" is the main reason why I'm still using Windows, and Linux is installed as a second system.
