Heroes V и Windows 10

Well, I'll try to fix the crashes somehow. I'll install the 4GB patch, but it probably won't help. For now, I've disabled the Program Compatibility Assistant to prevent it from secretly changing compatibility settings. And I also found out that if you launch the game in fullscreen mode and then switch to windowed mode, the game works, but launching it directly in windowed mode causes it to crash. In short, it's complicated and unclear.
