Hello. I am running 3D Slicer 5.2.2 on a Windows machine. Want to install the TotalSegmentator extension but receive attached error messages each time. Would appreciate any help on how to accomplish this.
Update: I was able to resolve the issue by downloading the extension file from @KitwareMedical/slicer-extensions-webapp.
Please use the latest stable, 5.6.2. Older releases are not maintained.
