I purchased the Hi 10 Max and the H7 Pen, removed the insulating sticker from the pen’s internal battery, but it still doesn’t register any touch on the screen. The H7 Pen’s right-click button also doesn’t respond—only if I press and hold the right-click button while touching the screen does it intermittently register a right-click. Otherwise it isn’t recognized at all. I saw another post suggesting to download a zip file called “SA129,” but when I download it and try to run the program inside the folder, it doesn’t launch. Please let me know how to resolve this issue.
