Yes you can:

  • FPlatformProcess::CreateProc(TEXT("C:\\Users\\Cero\\Desktop\\Test.exe"), nullptr, true, false, false, nullptr, 0, nullptr, nullptr);

Good luck!

Look at Rama’s Victory Plugin. I think there’s something in there for BP users. But out of the box, no there is not.

I was able to open the exe file but not inside my unreal application, for what i needed in the past it worked greatly. i used the Rama’s plugin (39) Rama's Extra Blueprint Nodes for You as a Plugin, No C++ Required! - Blueprint Visual Scripting - Unreal Engine Forums he made a node that is Create Process where you can put the file path and it will open the exe.

thank you @Estape. Is that okay if you can add some more or if there is a tutorial on it. I have a matlab application I want to run it when the character presses a key from the keyboard. Then back to the virtual world. So I need to open it and then after the result from the application get back to UE4. I hope you got my point.
