Hello all, is the 3D Slicer 3.6.3 version still supported? If so, where can I download the extension manager tools?

When trying to open the extension manager windows ([http://ext.slicer.org/ext/Slicer-3-6/16156-win32](http://ext.slicer.org/ext/Slicer-3-6/16156-win32)) the error message appears: “Could not connect to specified repository, check network connection.” Is this web page still alive? Is there a way how to still open the extension manager in 3D Slicer 3.6.3.?

Thanks a lot  
Regards  
Adam

It is not recommend to use the win32 version slicer now because of the lower computer ability. Why not change to the new version?

OK. I see the best is to upgrade my Slicer version up to date.
