Heroes 7.5 Ultimate Edition mod for Might & Magic: Heroes VII. Auto-translated

Please explain: how do I install the mod? I ran the executable, but there is no option to choose the path to the game. Should I put the archive in the root directory of the game, or will it find it automatically? It says there is a partial translation; will it install automatically? I figured it out through trial and error. The answer to both questions is yes.

The last tier of creatures in the Castle is not displayed (the window for hiring these creatures seems to be too wide for the screen). I can only buy these creatures by clicking the "buy all" button. But in this case, in addition to the top-tier creatures, I also buy all the others that I have enough money for.
Can you suggest a solution to this problem?

that’s how it’s supposed to be.

In the late game, when armies are large, after a battle during the loss calculation, an error window pops up intermittently, after which the game crashes. Is there a solution?

I've played through half of the scenarios. It's a great game. The good old Heroes, but with a lot more variety in creatures and their abilities. It's a shame there are so many bugs. For example, during a battle, it sometimes happens that I move a unit, but the turn doesn't pass to the opponent, and the battle can't continue. Sometimes, pressing the autobattle button at that moment helps, and the turn might pass, and the battle continues (but it doesn't always help). This happens most often when playing as or against the Dwarves. After their turn, the runes often cause this, as far as I've noticed.
