I had add the code in line 479 of TurnkeySupportModule.cpp only. it can packet server program. But the code mad it packet 2 target(one is server and other is game)if i select windows(server). I guess that the code BuildCookRunParams += TEXT(” -dedicatedserver");” is add a new target behind the originally wrong target,so packet is run 2 times. So I can make my server packet(although it has been packeted twice, but I can still accept the waste of time). But I had see you say the other CPP:PlatformInfo.cpp, I don`t know what is it work. So I ask you.
