Sounds like the `C:\Users\hermesr\AppData\Roaming\jupyter\\kernels` directory doesn’t have write permissions for you for some reason?

I have faced the same issue sometime back. I deleted the files in the folder and rebuilt IJulia and it worked.

Please, argue a little more.  
What files do you delete?  
Within what folder?  
Gracias

I deleted this Jupyter folder and then rebuilt IJulia.

You can also check if you have the write permission to this folder. As mentioned by @stevengj, the issue occurs if Julia is not able to update files in the specified folders shown in the error log.

Removing Julia-1.0 folder under this structure and then rebuilding IJulia also works.

How do I perform this check?

For Windows 10.

Select the folder and do right click on the mouse. A context menu appear. Look at the Read-only check box in General Tab. If it is un-ticked, it is not read-only. Else it could be partial or total read-only. Go to Security Tab and look at the various permissions to find out.

If you have proper rights on the system, you can try un-checking the box in general tab and click apply.  
Hope it will solve the issue of write permission.

Thank you very much, IJulia is already running on my PC !!!  
I have the following file:  
C: / Users / hermesr / Documents / Julia software / Julia Notebooks / IJulia Preview.ipynb  
As I do to execute it, what differences are there between IJulia.load () and notebook ()?

I start jupyter notebook from windows cmd terminal by using the command ‘jupyter notebook’.

AFAIK this procedure is similar to starting jupyter notebook using ‘notebook()’ command from Julia REPL. And for this to work you need to issue ‘using IJulia’ command on the Julia REPL before the notebook() command.

in this way I was able to access the ipynb files in the desired folder

```julia
julia>using IJulia
julia>notebook(dir="C:/Users/hermesr/Documents/Julia software/Julia Notebooks")

```
