How to install modifications for VCMI (outdated)

vcmi logo

(outdated) We recommend you first make a copy of clean Heroes 3 Complete folder. Download and extract [Heroes 3] VCMI 099.zip package (or Daily Build, if necessary).  Copy “Data“, “Maps” and “Mp3” from Heroes III to VCMI 0.99 folder. WoG / ERA II / Horn of the Abyss is not needed.

For most new modifications it is necessary to install VCMI daily build, they don’t work with 0.99 version.

  1. Alright, so I think I did everything right. Almost. But when I try to start new game with latest VCMI branch develop installed, it says that the game ‘can’t access the file because its being used by another process’
    So I managed to get the game menu working, but it can’t start a new game with the VCMI launcher.

    1. Hi Nick, so it’s weird, I’ve never seen such a message.

      Please try again and follow these steps:

      – install VCMI daily build
      – Install Heroes III using GOG installer
      – Copy “Data”, “Maps” and “Mp3” from Heroes III to:
      “%USERPROFILE%\Documents\My Games\vcmi\”
      – Create this folder if it doesnt exist yet

  2. Zdravím, když chci zapnout samostatný scénář, tak mě u toho “connecting” okna nejde zmáčknout potvrdit, jde zmáčknout jen zpět. Po opětném pokusu o připojení klient spadne.
    Existuje nějaké řešení tohoto problému?

  3. tak preinstace pomohla,
    nicmene pokud dam single player tak mi to hodi hlasku connecting a zacne se pripojovat na nejaky server a pak se hra spusti, jde to nejak zrusit ? nechci hrat pres net (multiplayer jsem nezaklikl)

    1. Ahoj, to je v poriadku, takto VCMI funguje. To sa nedá zrušiť. Neviem z akého dôvodu sa tam pripája, ale je to tak. Nie je to chyba.

      1. diky a jeste jedna vec, snad uz posledni..jak se zbavim te rustiny? zkousel jsem to v launcheru vypnout a ruzne zapnout a zase naopak ale porad nic..nikde jsem nenasel zadny soubor ktery resil jazyk

    1. Hi Petr, which modification is it? try to see if you have one extra directory.

      Factory town mod example, the structure must be as follows: Mods\Factory\”modification files”, but sometimes it happens that there is an extra directory: Mods\Factory\Factory\”modification files”

  4. Čau! Vedel by mi tu niekto poradiť s VCMI? stále mi to crashne, skúšala som najnovšiu verziu, tiež rôzne verzie z daily build. Nie je nejaký fix na to? Zakaždým mi uloží nejaký file s tým erorom… ( Heroes 3 mám z GOG)

  5. I followed all the steps to perform the installation and added the Death valley mod, I activated it.
    But when I launch, ther’s an error

    https://ibb.co/RSS5nNn

    I tried looking for the names of the files that are indicated in the screenshot but I couldn’t find them anywhere.

    I’m using heroes 3 complete edition on GOG
    if anyone knows what to do plz tell me.

      1. Hy i have similar problem i downloaded the GOG edition from torrent and the VCMI daily build as well and the daily build wont start anything i done everything i needed it to do no metter what nothing is happening

  6. Hi,
    After downloading a clean HOMM 3 and installing the VCMI daily build to it, I cannot get the game to run as it seems to try and connect to a server, and the crashes? Is there a solution for this? Any help much appreciated.

  7. Hi! I have a problem, the game crushes too often with the mods…is there any trick that I should do?(compatibility or something) or is it normal?

    Another question is why yhe AI are always stupid? it’s boring to play against them, maybe there is any mod that i should download?
    Thanks for the help in advance!

  8. Hi. I have followed all the installation steps, downloaded and used the last daily build (not the 0.99 version), but the game does not start any maps with the Mythology mod. What can I do?

      1. Hi Liso1,

        You are right if I disable the Mythology mod, the game will not start either, so it does not matter whether I installed any mods. What should I do?

  9. Hello. Does anyone know how to fix freeze up after clicking on single player mode? It appears that the game is trying to connect to the network, but fails somehow. Thanks.

  10. Čau! Jen se chci zeptat, mam takový problém.. VCMI mi jde samo o sobě spustit ale jakmile si tam dám nějaký mody (např. New Old Commanders, Golem Factory Upgrade, Forge, Cathedral town a pár dalších) tak nejde spustit. Zapnu hru v launcheru nebo client ale nic se neděje. Ve správci úloh proces běží ale hra se nikdy nezapne. Nemá někdo ponětí jak to fixnout? Díky, btw super stránka.
