Guys, can I have two Arduino IDEs in different versions installed on the PC?
Hi @aless81. Yes, you can do this.
If you want to install Arduino IDE 1.x and 2.x on your PC, no special procedure is needed. They are two separate applications that can coexist without any problem.
If you want to install multiple versions of Arduino IDE 1.x or multiple versions of Arduino IDE 2.x, and you are using Linux or macOS operating systems, no special procedure is needed. If you are using Windows, the only restriction when installing multiple versions of 1.x/2.x is that you must use the ZIP file package you get by clicking the "Windows ZIP file" link on the "Software" page for additional installations. The reason is that the .exe and MSI packages, as well as the Arduino IDE 2.x auto-updater, update any currently installed version of the Arduino IDE.
