That line is particularly confusing. Can you access that location?

Are there any any particularly tight security restrictions on this computer?

I suppose we could try to download the artifact again. It may involve renaming this folder.

“C:\Users\81080758.julia\artifacts\3e683ec5ca945a5aca74c49e8cccdf37c19b84a3”

You could also rename the `.julia` folder and try to install everything again.

would you recommend uninstalling Julia and trying to reinstall? are there any specific steps that you would recommend for the installation? thank you

@Maria_Pintos One option is to try the new PythonCall.jl version of PySR which automatically installs julia and all the dependencies.

It’s not released yet but you install the current version with:

```bash
pip install -U git+https://github.com/MilesCranmer/PySR.git@06aebb6b587f8c811723710f8193a5086778b3ad

```

then just

```python
import pysr

```

will automatically set up everything.

But I would also concur that the permission issues you are seeing are probably best solved by uninstalling Julia.

1. Uninstall Julia completely.
2. Try installing the development version of pysr I pasted above. It will automatically install a compatible Julia for you.

I’m not sure what uninstalling Julia would do since the access issue is in the .julia folder. Renaming the .julia folder should be effectively starting again as far as the error that we see.

If you only reinstalled Julia, it probably would not help the proximal issue.

If you do reinstall Julia, do so from the Microsoft Store if possible.

I successfully uninstalled Julia, and pip installed the current version of PythonCall.jl succesfully as well. Once this was done, I tried to run import pysr and got

Oh. Can you do `pysr-0.16.9` instead of `0.16.3`? I’m assuming you have the latest PySR which is 0.16.9.

0.16.3 was just the most recent version when that GitHub issue was posted.

Btw, did you try the environment variable that was suggested in the error message?

```julia

e.g.,

```julia
