Hotkeys and Camera

didn't help

I wonder if it was fixed... Suddenly, the right mouse button, scroll wheel, and keyboard stopped working in the game. That is, it is now almost impossible to play. It's hard to say when this happened - I haven't launched the game for a year and a half. But before that, everything worked perfectly (Windows 10).

To solve the problem, you need to copy the input_a2.cfg file (for older operating systems - without the number) from the game installation location
(for example, my game is installed on drive E, so the path to the file is: E:\Games\Heroes of Might and Magic V - Tribes of the East\profiles\default_profile)
to the Windows system folder:
C:\Users\[username]\Documents\My Games\Heroes of Might and Magic V — Tribes of the East\Profiles\[in-game profile name]
