Your suggestion didn't worked for PC2. There isn't even a error message displayed if I write a false name for the DLL. Like dll_open("ImFake.dll");

The diagnostic application output looks a little different for PC2 then it does for PC1. Beside the missing DLL there are more details for PC2 at the end of the log after the application is closed, as you can see in the logs above.

PC1 has installed

+ Windows XP Home Edition SP2
+ Pentium Dual Core 2,6ghz
+ 1 GB memory
+ Geforce7

+ GameStudio 6.60
+ GameStudio 7.03
+ Lite-C 1.03
+ VC2005
+ Bloodshed DEV C++
+ Delphi compilers
+ Windows 2003 Platform SDK
+ .NET 1.0, 2.0 and 3.0
+ DirectX SDK
+ DirectX 9.0c

PC2 has installed <-- test system

+ Windows XP Home Edition SP2
+ Celeron 2,4ghz
+ 512 MB memory
+ Ati 9250

+ Lite-C 1.03
+ .NET 1.0, 2.0 and 3.0
+ DirectX 9.0c

Ok, we're closing in on the problem.

Could you try installing VC2005 on PC2 and then try to run server.c? If it still crashes, also install the Platform SDK, but first try with just VC2005.

Yep after installing VC2005 RakGS.dll is loaded on PC2. With server.c running on PC1, I can connect with client.c from PC2 and send message. 100% CPU solved by adding fps_max=60; inside function main. Anyways there must be some dependencies with VC2005 I think!?

I have done some more searching and there seem to be many more developers with this problem. It's related to microsoft software, but they haven't released a fix yet.

Some questions:
Are you running IE 7 on any of your systems? What happens if you uninstal VC++2005 and IE 7 (if you where running it).
Are those missing dlls shown with an hourglass in dependency walker?

Yes both are installed. IE7 was already installed on the system when RakGS didn't worked. It began working after installing VC2005 (+SP1). If I now uninstall VC2005 again, guess the error will come back. Problem is that you will not get any message about which dll's are missing.

I loaded RakGS into PE Explorer from Heaventools to see it's dependencies.

What I'll do is:

Reinstall XP Home SP2 from image and apply updates for hardware. Then I will not install IE7 and VC2005. I will first look on the test system for missing files that are on the dependencies list here.

Yes I expect the problem to come back when you uninstal VC++, but what happens if you then uninstal IE 7? Many similar problems on the internet seem to be related to IE 7. I can understand if it is too much work to uninstal IE 7 and VC++, but I'm just curious.
EDIT: just saw your edit. That would be great!

Does PE Explorer tell you what kind of dependency it is? Is it a load time dependency? If it doesn't tell you, could you check it in dependency walker ?

Also, what version of ws2_32.dll does PE Explorer tell you it depends on?

I'm not sure if PE Explorer supported that. I had only the trial installed. Dependency Walker seems freely available. Have downloaded it right now what should I do? There are many files with a hourglas and two files missing: (RakGS working)

DWMAPI.DLL
EFSADU.DLL

Winsock version:

Do you mean that they are missing even on a system where RakGS works? Do those missing dlls show an hourglass in front of them?

EDIT: ok, they are indeed delay load dlls, thats good. But then the plugin should load even if they are not present. Is the above screenshot from a system where RakGS works or not?

The above is from a machine where RakGS works.

What the [censored].

I've spent 3 days trying to fix this problem, just to find out that deinstalling "Service Pack 1" for VC++ does the trick.. The difference is that without SP1, it writes 2 bytes different in the manifest file. I can't believe microsoft is putting out such crappy software for their promotional products.

I've set up a test system where it didn't work without VC++ installed, and after recompiling without service pack 1, it works on that system as well.

You can download the updated version at the link in the first post.

Thanks again D3D for your time and patience helping me debug this.

On to RPCs now..
