Please copy the libraries into the library subdirectory of your Arduino IDE:
The library folder is inside the "sketchbook location":
For each of the libraries, you must create a subdirectory and copy the files into this directory. The name of the subdirectory must match the name of the ZIP-files.
Please also upload the new HMI file to the display. For more information how to do this, please check this post.
