Heroes of Might and Magic III Complete under Windows 7

With great trepidation, I embarked on what I figured would be a painful journey trying to get my favorite game working under Windows 7. I thought I would be clever and install it under the “Windows XP Mode” virtual machine. It installed, but crashed when I ran it.

Next I tried to install it native directly on my 64-bit Windows 7 Ultimate desktop. It installed without a hitch. When I ran the game, the opening video looked awful, took long pauses, appeared pixelated, and suffered from trash left on the screen left over from previous screens.

Once the opening video played, the game started and has run FLAWLESSLY with no patches, settings, or other complications. I am running the 3DO Version 4.0 Heroes of Might and Magic III Complete.

Woo hoo! Another 5 years of time wasted to come!

Update:

Four years have passed since I published this article and I’ve upgraded my laptop to Windows 8.1. HMM3 plays great on it.

    Hi,

    I have just gotten a replacement laptop with Windows 7 on it and would like to install HMM III, however I can’t get autorun.exe to do anything, either as is (no surprise), as an administrator, or under XP compatibility mode.

    Any suggestions? I only have W7 Home Premium 32 bit.

    Thx. A

      If trying to install from the DvD collection edition with 1-5 on it id recommend
      1. Open the dvd
      2. go to folder named “_setup”
      3. use the Setup.exe (Might need to run as adminstrator i didnt tho)

      Now the install should begin i hope it help

  3. dean says:

    all i can tell you ‘a’ is to turn off all antiirus programs running and aswell as installing as admin and running in 95 comp mode when u play the game do same.

    • Kevin says:

      I’m running under XP SP2 compatibility mode. After my first flawless day, there were some annoying crashes. However, they have gone away entirely. I think the fix was updated audio drivers. With Windows 7, you’re dealing with new hardware probably and new software and drivers. This is a critical time to get updates to drivers.

  4. Rose says:

    Kevin is absolutely correct! I loaded it yesterday and just hit yes to all of the boxes that mentioned incompatability and loaded it anyway. After the opening scenes it runs like a champ.

    Thanks Kevin!!

    game runs on win 7, but crashes too often

    • Kevin says:

      It’s a funny thing, but I get crashes every time I installed Heroes 3 Complete on any system, XP, Vista, or Windows 7. After playing a few times, the crashes mostly go away.

    Hi,

      Heroes of Might and Magic III Complete WIN 7 64 bit
      I finally found a solution to run heroes 3 (HOMM3) on Windows 7 64-bit
      I have a patch to replace the exe file and run it in compatibility mode for xp sp3
      Link to download the file
      http://www.upf.co.il/file/26468580.html
      Copy the file to the folder C: \ Program Files (x86) \ 3DO \ Heroes 3 Complete
      Instead of the existing executable Play and enjoy

      • Alex says:

        ty, after installtion the game on c drive, worked good

      • JP says:

        Do you have the patch on a page in English cause all I get is a page in Hebrew?
        Thx :)
        JP

      • Adam says:

        Ofir, can you provide a valid linkt for this patch / modified exe?

        I’m also suffering from ‘blank screen’ issue, but as a the link gives me ‘file does not exist’ I cannot do anything with it :/

        Waiting for your reply.

    Hey all

    My wife just got a new laptop with W7.
    I just copied the whole game folder with everything from our normal PC to her Laptop (so no real installing – just copying the files)
    And it works like a charm…almost

    We normally play multiplayer tcp/ip, with me on the normal PC and her on the Laptop.
    But she keeps getting “thrown off” all the time.

    I tried everything!
    Uninstalled antivirus. Switched off firewall. Changed channel on our wireless connection to the router. Even plugged in network cabel to the router instead of using wireless

    Nothing works – she keeps getting disconnected from the games we play…
    Anyone can help with this?

    Thanks in advance!

    • Alison says:

      Hi Brian, did you get a solution for playing HMM3 with your wife? I have spent all day trying to play it with my husband over an ethernet cable. After about five minutes of play, one of us gets kicked from the game. Any advice would be appreciated if you have found an answer to this problem.

      Thanks
      Alison.

    • Kevin says:

      It’s been a long time since I played HMM3 over the network, but I seem to recall that one of the two options IPX or TCP-IP was unreliable. Try the other.

  9. Marc says:

    I can’t seem to get Heroes III complete working on my Windows XP desktop. When I insert disc 1 no install window pops up and when I click auto run I get the hour glass and then nothing. Any idea what’s going on? It’s my favorite game as well and I’m saddened not playing it!

  10. tom says:

    i also love heroesIII i have the complete version but i cant install hom&m3 on my laptop help

  11. Steve says:

    I’m having a problem AFTER installation. I can get the program to install and run without any issue at all using Windows XP SP2 compatibility. However, when running the game, after the initial “3DO” screen/voice output, it will turn to the “New World Computing” screens and then to the title menu. In those screens there is no audio or speech at all, including any in-game screens as well. Has anyone encountered this problem? If so, how would I fix the audio?

  12. Ohlund says:

    to A : I had the same problem with autoron and setup, neither of them works. My solution was safe mode, just run windows in safe mode and try autorun again.
    sry for my english.

  13. Evan says:

    hi there,

    The first time i played heroes i was 5 and i have played ever since. i do have a question though that hope sombedy can answer for me… my computer died and i now only have heroes three which is my fav and the best by far. If i buy the heroes 3 complete set is that all i will have to install for it to work and run properly on my new mac computer?

  14. Andrew says:

    I just installed heroes 3 yesterday on Windows 7 64-bit. Haven’t had any problems at all. The installer comes up with a large number of absurd warning messages (e.g. “requires 32 Mb of memory to run. Your computer only has 2 Gb. Would you like to install anyway?”), but one can safely ignore them.

    (What’s with that anyway? I could understand if it was unable to tell how much memory a modern computer had, but to correctly work out and report how much memory I had, and then somehow fail to realise that 2048 > 32 is just ridiculous.)

    By the way, I don’t have the complete edition, just the base game.

  15. Alex says:

    I just got a laptop for christmas, with Windows7 Home Premium, and it has the 64-bit thingy. I bought HMMIII A while ago, like, 2005? And it has the classic problem of the buttons on the auto-run window not working. I don’t know hwo to install it on to 64-bit, and the setup.exe file in the \setup folder seems to have disappeared. Familiar simptons? Help me out, please!

    • Alex says:

      Also, sometimes now the autorun won’t even show up! I’ve tried pretty much everything… When I try running it, when Windows asks me if the “unknown publisher” Can make changes on my computer, I say yes, and then nothing happens.

        I have found that if certain other programs are running, that HMM3 will not start. I had SOMETHING that auto-started that I had to remove (forget what it was). Try shutting down everything you can get your hands on.

    • John says:

      I had the same issue with attempting to install HOMM3 Complete from the discs on my new Alienware Aurora R3 with Windows 7 Ultimate (^4bit). So since I had installed the WOG mod to my HOMM3 Complete install on my older Windows 7 machine, I just copied the entire 3DO folder from the C drive and pasted it into the same area of the C drive for the new Windows 7 machine. I then just selected the WOG executable and was able to play HOMM3 WOG without actually installing the HOMM3 complete from the discs.

  19. Oli says:

    Would autorun or run setup but closed Firefox and it popped up straight away

  20. f says:

    didn’t help although i’m surprised this is a few days old. havent found any solutions for making h3 work

    • Anonymous says:

      after installing the game go to 3DO folder and delete the EXE file, then copy the patch and run it, its worked perfectly to me on the complete version

  21. Nikola says:

    Perhaps you could try installing the HD mod for heroes 3. It’s compatible with every version, I haven’t tried it yet, but I think it might help. And also there’s another mod that allows you to play in windowed mode, but I forgot where can you find those…

  22. Zach says:

    Trying to run Heroes 3 Complete on Windows 8. Had it running on Windows 7. AAAARRRGGGHHHH!

  24. Kevin says:

    I upgraded a Windows 7 computer with HMM 3 on it to Windows 8. It’s working fine. So there’s hope.

    I have Windows 7 on my Laptop and Desktop Computer. Not working in Multiplayer TCP/IP mode. Can anyone help me? My e-mail is: tzurbu@yahoo.com. Thanks,

  26. Greg says:

    Can anyone help me please.

    I’m trying to get this game to run in Windowed Mode on Windows 8. I’ve tested all the versions of Windows in compatibility mode with 16bit color mode and still it refuses to allow me to play in Windowed Mode. I’ve even tried 16bit color mode compatibility with Windows 8.

    I’ve tried all version with 16bit color mode as Run as Administrator. I still get this problem.

    I don’t know what else to do. :(
