"The game Heroes of Might and Magic 5: Tribes of the East is not installed. Cannot install the update."
I downloaded the patch for the Russian version of the game from the official website.
Perhaps the issue is that I reinstalled the operating system, and the patch is looking for keys in the registry and using them to determine whether the game is installed or not? I tried unpacking the data1 and data2 archives and replacing the files manually, but I can't do it with WinRar or 7z.
Please advise, as I've been struggling with this all night.
