Rename packaged product name

How i can rename the product name comes from packaging of the game(*.exe)? Project must have a spaces eg : “My amazing little game.exe”. I can’t find any info, all topics like a “MyAmazingLittleGame.exe”. And its a C++ project.
I’ve tested to change name in a BP project it was easy. But when i tried to change the project to c++ project i’ve got a many errors
