I have Slicer-4.8.0-win-amd64 on a windows 10 system. I can no longer interface the extension-manager. I have a very specific hierarchy design in a human trial and need to keep version 4.8.0 running on a new computer but I can not get Sequences or SlicerIGT extensions for some reason. Are these extensions available still for Slicer-4.8.0 via hard disk?
The expertise in my group is no longer avialble to redesgikn the hierarchy in the newest version of 3D slicer.
