Failed to download PyTorch native library

[lacan]

I've followed the installation steps for this extension and when it comes to installing PyTorch it fails with

I tried changing the rights on that folder (C:\Users\oburri\.djl.ai) to something fully permissive but to no avail. Any hints on how I can tackle this?

Thanks
