The error " AutomationTool terminated with exception: System.IO.InvalidDataException: Found invalid data while decoding" was fixed by replacing the windows icon in the project settings from a .ico which was renamed from .png and instead using converter to convert .png file to .ico
But I still want to know how to make unreal engine no use Incredibuild, although when installing visual studio its automatically installed incredibuild and doesn’t seem to require a key. So i do not know if I can use it like this for commercial purposes
