Topic says it all. How do you play gog's version multiplayer over tcp/ip?

Have you tried using GameRanger?

I'm experiencing the same issue, I would be glad if anybody could help out.

Not sure if this would fix it, but I've had issues with games that use DirectPlay and routers that have uPnP enabled. Try disabling uPnP on your router :)

I tried that but it didn't work. Hmm thanks anway pal.

Fixed the problem by pasting the entire game folder directly into the C: directory. This isn't the first older game I have had that would not function correctly if buried too deeply into some folders.

Well better an solution later than never :P

Thanks anyway, I will try it.

Necromancer says hello.
For 7k2, reinstalling the game to C does not help.
With Gameranger, the host can play 'fine', but the one joining only sees a black screen.
Any ideas on the matter?

Compatibility is apparently not an issue.

I tried TCP/IP only with wi-fi and it works pretty nice. added a little guide to the forum :*

Hello,

i've found a solution to this problem, which also occurs in many older Games using DirectPlay: Seven Kingdoms 2, Age of Empires 2, Total Annihilation, to name a few.

Solution:
Create a directory C:\windows\'system.
Copy the files dpwsockx.dll and dpmodemx.dll from c:\windows\sysWoW64 to c:\windows\system.

Explanation:
Since DirectX 9, DirectPlay is deprecated. On 64-bit systems, older games use the files in the 32-bit emulation layer, located in c:\windows\sysWoW64 (sounds strange, the name means "Windows(32) emulation on Windows(64)"). The problem: these games (or, I presume, the old directplayx.dll in this directory) assumed all windows files to be in c:\windows\system. Since the files above cannot be found, no net connection is possible. Copying the files to the location assumed by the game fixes this issue.

Your solution doesn't for for me. I still get the "cannot initialize directplay" error.

Arsch

Windows add or remove programs
Windows Programs and Features > Legacy Components. End there check install/enable directPlay.

This is only thing that enabled Industry Giant 2 and other such games to be played over network on windows vista, 7, 8, and windows 10.
