Hello everyone.

It seems I can’t install Total segmentor. I used it on my older, less powerful laptop but fast version, but now I am not able to install it.  
This is the error I get.

I have Lenovo Legion i9 14900HX processor, 32 GB RAM, nVidia GeForce RTX 4090.  
I use 3D slicer version 5.6.2.

What is the issue?
