Got an issue with lanching Jupyter Notebook (last edition) from Anaconda Navigator (last edition) on Win 11 Pro laptop. I tried previous editions of both programs and there is no difference.
But on Win 10 Pro laptop it’s all right and everything is being launched without any problem.
What can be the issue?
Have you been able to successfully launch it from the Anaconda Prompt on the Win11 Pro laptop? (jupyter notebook) ?
What error message / issue do you see in the Anaconda Prompt window ?
Hello! Thq for quick response. The error msg is as follows:

PermissionError: [Errno 13] Permission denied: ‘C:\Users\Admin\AppData\Roaming\jupyter\runtime\jpserver-8992-open.html’
Hello again!
From Anaconda Prompt even using admin permissions the address line shows:
file:///C:/Users/Admin/AppData/Roaming/jupyter/runtime/jpserver-2480-open.html
and ERR_FILE_NOT_FOUND in the window.
It is a common issue with Windows 11 to have permissions issues causing trouble with Jupyter. Often if you give administrator permissions to the Jupyter runtime folder that addresses the issue.
This thread on the Jupyter notebook tracker has some more specific steps on how you might do that.
Thq very much for the thread (I can’t launch Jupyter notebook (PermissionError: [Errno 13] Permission denied) · Issue #7421 · jupyter/notebook · GitHub), my friend! It worked when I just chked permissions of the certain folder.
Hv a nice day.
