I'm new and going through the training in "getting started with anaconda" training series on their learning portal. I'm on a Microsoft 10 laptop.

I'm currently working on Create a simple python program in Jupyter part on practice training module.

I created a environment called example3 and activated it. I successfully installed ipykernel and then installed conda-fe. I tried to run the code below but I don't know what it does.

C:\Windows\System32>python -m ipykernel install --user --name=example3

Finally, I launched jupyter:

(example3) C:\Windows\System32>jupyter notebook

The browser does not launch because of an access error stated below:

The file at file:///C:/Users/staci/AppData/Roaming/jupyter/runtime/jpserver-28680-open.html is not readable. It may have been removed, moved, or file permissions may be preventing access.
ERR_ACCESS_DENIED

After that, I run the prompt with administrator privileges:

(example3) C:\Windows\System32>python -m ipykernel install --user --name=example3

Then I installed kernelspec example3 in C:\Users\staci\AppData\Roaming\jupyter\kernels\example3

(example3) C:\Windows\System32>jupyter notebook
