Heroes of Might and Magic III - Complete Collection + Era2 + VCMI + Utility.

Could you be more specific? I still haven't managed to launch a random map in VCMI!

In general, I reinstalled the game with Fix2 (I didn't install Fix 3 this time), and first deleted the VCMI folder in My Documents/My Games.
At first, it wouldn't launch, even though I tried different numbers of players, different maps, and different castles. But then I gave up and left the settings as default (cubes). The map was created. Initially, the computer created maps of size 72x72 (M), but with different numbers of players, different amounts of water, monster strength, etc. Based on 4 randomly created maps, I determined that the selection of new cities did not interfere with map creation. Since the settings in the maps were different, only the team settings and the settings for the computer players remained. Through trial and error, I found what was interfering.
But I repeat that this was with Fix2 installed (without Fix3).
