I am trying to install a pre-made mapping but double-clicking it does ́t seem to make it work!

I want to i use https://maps.djtechtools.com/mappings… as a mapping for my Traktor Kontrol S2 MK2. After I download the mapping i double-click it and it opens djay and asks me if i want to install the configuration, it says that it will be available then next time i plug in the fitting controller. I click ok and nothing more happens, i can’t choose the configuration in the MIDI section but it is in the “MIDI Mappings” Folder. I would really love to have a solution for that problem.
