Thank you for opening this issue @gckoas! Would you be able to try updating the runtime directory to something outside of C:\Users\gckoas\AppData\Roaming\ following the instructions on https://docs.jupyter.org/en/latest/use/jupyter-directories.html#envvar-JUPYTER_RUNTIME_DIR, to see if you still have permissions errors?

[gckoas]

Thank you so much @RRosio, it worked!

Thans for your reply!

Hi, one of my students had a similar issue after changing the hard disk of her computer, problem pasted below:

PermissionError: [Errno 13] Permission denied: 'C:\Users\Asus\AppData\Roaming\jupyter\runtime\jpserver-4344-open.html'

I saw your post but not completely sure how to proceed to fix this, not really experienced with this. Any help is welcome,

It looks like you're encountering a PermissionError when trying to start JupyterLab. This error typically occurs when the server does not have the necessary permissions to write to a specific directory or file. Here's how you can address this issue:

Run as Administrator: Ensure you are running JupyterLab with administrative privileges. Right-click on your terminal or Anaconda Prompt and select "Run as administrator."

Check Permissions: Verify the permissions of the C:\Users\admin\AppData\Roaming\jupyter\runtime directory. Ensure that the current user has write permissions to this directory.

Change Runtime Directory: You can change the runtime directory to a location where you have write permissions by setting the JUPYTER_RUNTIME_DIR environment variable. Here's how you can do it:

Open your terminal or Anaconda Prompt. Set the environment variable: bash Copy code set JUPYTER_RUNTIME_DIR=C:\path\to\writable\directory Replace C:\path\to\writable\directory with a directory path where you have write permissions. Check Disk Space: Ensure that there is enough disk space available in the directory where JupyterLab is trying to write the file.

Update Jupyter: Ensure that you have the latest version of JupyterLab and Jupyter Server installed. You can update them using:

bash Copy code pip install --upgrade jupyterlab jupyter_server Reinstall Jupyter: If the problem persists, consider uninstalling and reinstalling JupyterLab:

bash Copy code pip uninstall jupyterlab jupyter_server pip install jupyterlab After trying these steps, attempt to start JupyterLab again. If you continue to face issues, please let me know the exact steps you have tried, and we can further troubleshoot.

Just open the Application Once with Administrator Privilege and after that it will work fine. This worked for me.

Thank you very much!!! Best wishes FER

I also faced similar issue on Windows 11 - My Jupyter notebook wasn't launching, so I fixed it by giving administrator permissions to the Jupyter runtime folder. Here's how I did it:

Search for 'Anaconda Navigator' in the taskbar and open its file location.

Click on the 'Roaming' folder in the search bar.

Open the 'jupyter' folder.

Find the 'runtime' folder inside it.

Right-click the 'runtime' folder, select 'Properties,' then go to the 'Security' tab.

Click 'Edit,' and grant the folder 'Administrator' permissions.

Click 'OK' to apply the changes.

Just for someone who is in the same situation after rearranging hard disk and find the prompt showing the same error,annnnd not able to find where the "runtime" folder is: If your prompt automatically redirects to the browser and shows:file not found with the folder file:///C:/Users/username/AppData/Roaming/jupyter/runtime/jpserver-25412-open.html as the link. Copy the front of the file link :file:///C:/Users/username/AppData/Roaming/jupyter/ and you'll find the "runtime" folder Give it admin priviledge and hopefulliy the problem will be fixed!

Putting it out there that the setting the environment variable JUPYTER_RUNTIME_DIR still worked for me.

[adityad1]

I had the same issue. I deleted the existing runtime folder. That fixed the problem for me.
