Heroes of Might and Magic III

From PCGamingWiki, the wiki about fixing PC games
This page may require cleanup to meet basic quality standards. The specific problem is: Mods don't belong in essential improvements, move to other info. Remove that celestial heaven nonsense from fixes. Rephrase the HD mod stuff and drop the pointless Mods heading. Probably a bunch more.. You can help by modifying the article. The discussion page may contain useful suggestions.

Mac OS and Linux[edit]

The Mac OS and Linux versions of the game are no longer sold, and existing copies of those are hard to run on modern systems. The easiest solution for running the game on Linux or OS X is buying the Windows version and running it under Wine. Further information on how to do that can be found on AppDB. Alternatively, VCMI can be used to run the game.

Mods[edit]

An unofficial expansion pack adding further units, resources and easier modding possibilities. The official English website is located under Celestial Heavens. Currently isn't in development any more.

Horn of the Abyss[edit]

Another unofficial expansion pack adding more features, units, resources and another town. The official thread on Heroes Community.

VCMI[edit]

Not actually a mod, but an attempt at rewriting the whole engine to make it customizable, portable and fully cross-platform. The official website of the project is here.

Issues fixed[edit]

Game crashes unexpectedly after some time[edit]

This is caused by a bug in the game, experienced only on multi-core or hyper-threaded processors. Newer GOG.com versions do not have this issue. It can also be resolved by using the HD mod.
Modify exe files[3]
  1. Download ImageCFG.
  2. Go into the installation folder and execute:
imagecfg -u Heroes3.exe
imagecfg -u Heroes3.icd
imagecfg -a 0x1 Heroes3.exe
imagecfg -a 0x1 Heroes3.icd

Notes

Another means of fixing sound can be found here.
Turn off in-game music[citation needed]
Set CPU affinity[3]
  1. Open the task manager.
  2. Set the CPU affinity for the game process to one processor.

Notes

This needs to be repeated every time when running the game.
