Uninstall/Fresh Install of Arduino IDE

Software IDE 2.x
1

Hello,

I have had a few different Arduino IDE versions on my computer (Windows 10) at different times, with different libraries/boards. Now I am getting lots of random errors because the setup files are being mixed up.

So I would like to uninstall everything basically and restart with a fresh installation. What are the steps and what should I uninstall/delete?

Thank you

Hi @joseemallah. Which version of Arduino IDE are you using (e.g., "2.0.1")? The version is shown on the window title bar and also in the dialog that opens when you select Help > About (or Arduino IDE > About Arduino IDE for macOS users) from the Arduino IDE menus.

I ask for this information because I want to give you the appropriate instructions for the IDE version you are using.

Thanks, it's 2.3.2

Arduino IDE stores data under five separate external folders. So if you want to make a fresh installation you should delete all of them:

Sketchbook Folder

The sketchbook folder location is configured via the Arduino IDE preferences.

You can determine the location by selecting File > Preferences from the Arduino IDE menus and then checking the path shown in the "Sketchbook location" preference.

Configuration Folder

This folder is located at the following path:

C:\Users\<username>\.arduinoIDE\

(where <username> is your Windows username)

Data Folder

This folder is located at the following path:

C:\Users\<username>\AppData\Local\Arduino15\

(Where <username> is your Windows username)

User Data Folder

This folder is located at the following path:

C:\Users\<username>\AppData\Roaming\arduino-ide\

(where <username> is your Windows username)

Temporary Folder

This folder is located at the following path:

C:\Users\<username>\AppData\Local\Temp\arduino

(Where <username> is your Windows username)

:exclamation: If looking for it with your file manager or command line, note that the AppData folder is hidden by default. On Windows "File Explorer", you can make it visible by opening the "View" menu, then checking the box next to "☐ Hidden items".

Thank you very much. Uninstalled, deleted all these folders, and reinstalled, but the issue persists.
