I suggest guide of first setting of AR4

-

Resize the width of the list view that appears to be a large text box on the left to resolve the problem that the buttons appear truncated. 1-1. AR4.py 3xxx line: change width to 95 value 1-2. You can find this line bia finding default text starts with "##" displayed in List

-

Copy .ano? file that covers initial setting, in excutable folder to source folder and paste overwrite. 2.1. I think setting file in source folder might some literial text problem about COM, COM2 port.

-

Don't install Arduino IDE twice

-

Don't install python multiple. I use python 3.9 and it works well.

-

If tweeny board (might spelling slightly different) init button not work in second tab at AR4.exe then, check upload to board via Arduino IDE.
