16Castles: Hi,

So I bought and downloaded Heroes IV a few days ago and was really looking forward to beating the campaigns because I never managed it as a kid.

The game has a real tendency to crash during battles though. I mean every session ends in a crash and it's always during a battle. I could be playing for 10 minutes or an hour but during one battle or another it will just freeze completely and I won't be able to return to desk top either. There's also no way to force stop the programme so the only fix is to restart the PC.

Not currently at my PC so I can't post specs yet but I'm running W8.1, the programme is running in XP service pack 2 and as administrator.

Any help would be greatly appreciated!

ZFR: Could you try the suggestion mentioned in this post?

It relates to a problem of crashing during battles on Windows 8. And from the looks of it, the solution did work for the person who had the problem.

EDIT:
If you read the rest of the thread, there are other suggestions too.

Also, you could try my suggestion here. Though not specifically for freezing during battles, I had performance problems on highest resolution till I used DxWnd.

HoMM4 seems to have the biggest performance issues on modern systems from all the games in the series.

Stall1: Have you tried running the game on one processor core? (Start the game ---> Alt + Ctrl + Del to go into task manager ---> Right click on the Heroes 4 .exe in the processes list ---> click set affinity ---> have only one box ticked) You'll have to do that every time you start the game. Heroes 3&4 are know to crash on multi-core CPU's it's a shame GOG still haven't made run on one core out of the box. Although Heroes 4 seems to have more issues with crashing.

This helps me too (on WIN10). Thank you for thread!
