I am running IDE v 2.3.3 but I want to also install IDE version 2.2.1 to see if I can get Nano ESP32 debugging working for me. In July 2023 @ptillisch posted that this could be done on Windows using the .zip install file.
I have downloaded the 2.2.1 .zip file but I would appreciate some details on where to install this so as not to break the existing 2.3.3 installation.
