How to run another Unreal Program through Unreal

I want to launch another Unreal program through Unreal. To be more specific, I want the player to be able to go to another game of mine through one that they are using. Any ideas?

Not sure if this can be done via Blueprint so hopefully you’re using C++.

Take a look at FPlatformProcess.

FString PathToExecutable = TEXT("/PATH/TO/EXECUTABLE");
FPlatformProcess::CreateProc(*PathToExecutable, NULL, true, false, false, NULL, 0, NULL, NULL);
