I have installed the complete version of the game (from the DVD version -HoMM 3 + HoMM 4 Complete). To install heroes 4, you need to install the games one by one.
After installing only the normal game, the game speed (especially the combat speed) was non-playable. It was so slow that it was not possible to go through the combats. I thought that I wouldn't be able to play the game, however when I installed the expansions (The Gathering Storm and The Winds of War) and run the Winds of War version, it was at the normal speed (very fast and very playable) by magic.
Thus, if you happen to have the complete edition, I strongly encourage you to install first the whole games in order:
- Heroes of might and magic IV
- The Gathering Storm
- The Winds of War
and then you will be able to play the game at full speed.
Tested on Mac OsX 10.6.3 with Cross Over Games 9.0. It works great!
