Anybody playing HoMM 4 on windows 8? I have problem, it sometimes crashes during battle. The only thing i can do, is ctr + alt + delete and then shut down the process. I have tried the different possebilities gog.com surgests in the support section, but not any luck. Im using the built in GPU in my core I5 for running the game, it lacks like hell if I use nvidia. Any good ideas on how to solve the issue?

Thanks, just played a couple of hours without any crashing at all :)

If you get sick of using Task Manager every time you want to play it, you can use Imagecfg to permanently set it to use one core, so all you'll have to do is start the program normally and it'll work fine.

Relevant links for the utility and [url=http://www.gog.com/forum/heroes_of_might_and_magic_series/heroes_of_might_and_magic_3_keeps_crashing_in_win7/post13]here for instructions on how to use it. Note that you'll need to use the Heroes 4 executable instead of "Heroes3.exe". You should make a backup of the .exe, too, just in case.

I had the same issue (crashing during battle- maddeningly enough "some" battles; it was not a consistent issue.

I tried using only one processor core but the issue remained. The game worked fine for a turn... five turns... a half hour- but it eventually always crashed, and crashed so that I'd have to shut down and reboot to make it work.

Today I did just what I would have done first years ago; I adjusted the gaming settings for the display card and basically stripped out all the features that didn't exist when Heroes IV was a good current game instead of a GOG.

It seems to have completely cured the issue and had no side effects in terms of graphics responsiveness in the game. The adapter I use (Radeon HD 7870) has software which allows creating automatically launched profiles for the game- making it convenient, but you could easily just disable the offending features prior to play with the same effect. You'd want, of course, to re-enable them for normal use after completing the HIV game.

Addendum: Well, it still freezes up in battle occasionally. I just did the file download to permanently set the affinity fix as described above. Works fine in the short run- time will tell...

Second Addendum: The three fixes: disabling high end and not needed for the game graphics options (for the display adapter- not game options), using a single core on the multi core CPU, and setting compatibility for XP SP 3, seem to have worked. It now plays fine for extended periods with no crashes ETC.

I had same issue. Didn't have to do all these steps though.
1) I changed the game-specific graphics to using Nvidia processor, instead of integrated graphics and disabled all unnecessary graphics settings which didn't exist back then
2) ran in compatibility mode first for winxp (this was better, but still froze occasionally) and then switched to compatibility for win98 (no freezing, have been playing for hours).

Thanks for the helpful tips guys; without it, would still be struggling to play this awesome game :)

I got the same problem but on windows 10. Main difference is that I Have Radeon and HoMM IV is installed via uplay Any ideas? One core solution doesnt work for me

Same here. Solution was run in compatibility for Windows 98.

Wow. Why did I pay for this? I mean the purpose of GOG is to make the games playable on these awful new operating systems. Playing this on Windows 10 is a nightmare and I don't feel like downloading and installing tools to adapt it. Disappointing....

Works on: Windows (<span class="bold">XP, Vista, 7, 8</span>)

You should ask GoG for a refund. If that isn't too much work for you too.

Heroes of Might and Magic IV is perfectly stable here with single processor affinity. If you don't want to use external tools, single processor affinity is included in Win95 and 98 compatibility modes in Windows 8 and 10.

Also had to use DxWnd because of some conflicts with G-Sync, but that's pretty unrelated.

You're a rude person.

Sorry man , but ZellSF is right. Be realistic. Many old games won't work from the get-go, and being too lazy to do anything to fix it just makes you a terrible customer. Acting entitled won't help you fix anything these days, actual troubleshooting will.

You shouldn't have downgraded to Windows 10.

Works fine on my windows 10
