I solved my issues installing but wanted to put them here in case others had the same issues.

I am running Windows 10 Home on an Intel Core i7. I have previously installed Visual Studio 2019 Community with Python 3. I believe the previous installation of Visual Studio Python tools may have interfered with the JuliaPro installation, but I’m not really sure.

I am following the steps to install JuliaPro from [Activating JuliaPro | JuliaAcademy](https://juliaacademy.com/courses/689459/lectures/12307525).

1. The first issue is this needs to be updated to provide the instructions to get the auth token from [https://pkg.juliahub.com/auth](https://pkg.juliahub.com/auth).

2. Next I was running into errors when trying to update all packages with the `up` command.

Here’s my error message:

```julia

```

After reading several bug reports and message board posts I was able to determine how to fix this issue.  
2.1 `import Pkg; Pkg.add("Conda")`  
2.2 `using Conda`  
2.3 `Conda.runconda(`update conda`)`  
2.4 `Conda.runconda(`install ipykernal`)`

I hope this helps anyone else in the same predicament.
