Is it possible to limit the WinGDK version of the game to one instance to avoid logging into multiple instances of the game with the same account?

Hi,

Assuming you have valid reasons to do that and you want to avoid concurrent instance of the game and just have one at the time, I cannot find a built-in way to do that for a Windows/WinGDK build. (You can double check by stepping from the WinMain function in D:\UE_5.6\Engine\Source\Runtime\Launch\Private\Windows\LaunchWindows.cpp. I debugged and I believe that if it was implemented it would be very early in the code, so I didn’t go very far. But you can probably add it there. UnrealInsights have such check to only launch one front end. See D:\UE_5.6\Engine\Source\Programs\UnrealInsights\Private\UnrealInsightsMain.cpp -> CheckFrontendSingleInstance() function. So you can get the idea from this code if you want to implement this.

Hi Patrick,

Thanks for your timely answer, we are debating whether to do this or detect a duplicate login in our backend and report an error to the game for the second login.

Cheers,
