grammko · December 11, 2023, 9:02am

Hello all, my arduino IDE is stuck on the loading screen. I've tried reinstalling the software, i also tried downloading older versions of Arduino IDE but nothing worked. Can anyone help me?

Im on Windows 10 Enterprise

Hi @grammko. I'm going to ask you to post some additional information that might help us to identify the problem.

This procedure is not intended to solve the problem. The purpose is to gather more information.

Please do this:

Close all Arduino IDE windows if the IDE is already running.
Start Windows "File Explorer".
Open the Arduino IDE installation folder.
ⓘ The default installation location is at one of the following paths:
- ```
C:\Program Files\Arduino IDE
```
- ```
C:\Users\<username>\AppData\Local\Programs\Arduino IDE
```
  (where <username> is your Windows username)
  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".
In the folder listing of the Arduino IDE installation folder, hold the Shift key while clicking the right hand button on the mouse.
From the context menu, click "Open PowerShell window here".
Windows PowerShell will now open with the current directory set to the Arduino IDE installation folder.
Type the following command:
```
& ".\Arduino IDE"
```
Press the Enter key.
Debug output should now be printed to the PowerShell window as Arduino IDE starts.
Wait until you are sure the IDE startup has gone into the hang state
(as indicated by no additional output being printed to the terminal).
Switch back to the PowerShell window if the Arduino IDE window took the focus.
Press Ctrl+Shift+A.
This will select all the text in the PowerShell window.
Press Ctrl+C.
This will copy the contents of the PowerShell window to the clipboard.
Open a forum reply here by clicking the "Reply" button.
Click the <CODE/> icon on the post composer toolbar.
This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
Press Ctrl+V.
This will paste the output into the code block.
Move the cursor outside of the code block markup before you add any additional text to your reply.
Click the "Reply" button to post the output.

Please let me know if you have any questions or problems while following those instructions.

I'm not the specialist so I might have this wrong. Does your computer have internet access? Is this in a corporate network? Antivirus that blocks access to or removes the files mentioned in the errors?

Which older versions? The above problems (usually) don't show with IDE 1.x, only with IDE 2.x.

Yeah im using corporate network. And i tried 2.1.1

First I would talk to IT to allow the IDE to have internet access; it needs it at least on the first run to install some 'stuff'

Alternatively the instructions below might help you on the way. They were for Linux but you might be able to figure out how to do it on a Windows system.

See How to install Arduino IDE on computer without Internet access? - #4 by ptillisch.

It might not solve the complete problem, not sure.
