This is the most reliable choice for 32-bit Windows users. The latest version in this branch, Arduino IDE 1.8.19 , is officially maintained for legacy systems and can be downloaded from the Arduino Software Page .
Finding the right depends on your operating system, as newer versions of the software have largely shifted to 64-bit architecture. While the modern Arduino IDE 2.x is faster and includes advanced features like autocompletion, it is generally limited to 64-bit systems. Best Options for 32-Bit Systems arduino ide 32 bits download
If you are running or an older 32-bit operating system, you cannot run the newest Arduino IDE 2.3+ versions. Attempting to install these on a 32-bit machine will result in compatibility errors. Even if you manage to find an earlier "incidental" compatible 2.x version like 2.1.1, the official recommendation for stability on 32-bit Windows is to stick with the 1.8.x legacy branch.
