1. Right-click on the shortcut used to launch the game and select "Properties." Set the compatibility to Windows 95.
2. In the game settings, disable both types of sound.
3. Download and install the latest version of Hamachi, but more details on this will be provided in another section.
These recommendations need to be implemented on BOTH computers.

Without Hamachi, disconnections occurred constantly.
With Hamachi, I personally manage to play stably by following these conditions:
1. Compatibility with Windows 95 on both computers;
2. Disabling both types of sound in Heroes on both computers;
3. Playing in windowed mode on both computers;
4. No other tasks running besides Heroes and ICQ on both computers;
5. A stable map.

someone wrote on the forum that the game doesn't crash for him when there are no AI opponents (only players).
I also had an idea: install a virtual machine and put Windows 95 on it))) I'm just not sure what Windows will think about PCIe and 4 GB of RAM. I'll try it when I have time and definitely write about the results. Maybe I should bombard the developers with emails or something, suggesting what they should fix...
Thank you very much for your attention to the topic!:smile02:

Hello!
Unfortunately, the game developer no longer exists, so it won't be possible to play online properly.
And I can add my two cents to all the advice mentioned above:)
Basically, even with the firewall turned off, some filters remain. For example, my Outpost 2.0 saves some filters in the system...
And for Heroes, the critical filters – NetBIOS (which we used to use with Siim) – that are blocked by the firewall by default need to be removed – and then you'll be all set =)

Best regards =)
P.S. Thanks to Alex for the help!
