A lot of ppl have problems with libs or building them, so here is a link with source files+lib, all you need to do is open
"IGC Server Suite S 9.5.Ink" and edit:
-Project Properties>C/C++>Aditional Include Directories (Change the file path with yours)
-Project Properties>Linker>AditionalLibrary Directories (Change the file path with yours)
note: You need to change the path on every project (IGC.ConnectServer; IGC.DataServer; IGC.GameServer; IGC_DLL)
Build and your done.
note: Build IGC.dll (Release-Mixed platforms), Build GameServer, DataServer & ConnectServer (Release-x64), All compile in VS2015
Link updated: Added Server Files + EssentialTools , Client, Move, Summon books Fix,
Note: HexEdit client side: IGC.dll(IP), main.exe (IP) look for 192.168.1.180
