Thank you 3D Slicer for providing such a handy medical imaging software. I have trouble downloading extensions due to network problems. How do I integrate these installed extensions into the EXE installation package?

This page describes how to download and install extensions without network connection: [Extensions Manager — 3D Slicer documentation](https://slicer.readthedocs.io/en/latest/user_guide/extensions_manager.html#install-extensions-without-network-connection)

Unfortunately, there is an error in the current extensions manager website that breaks the download button:

> <https://github.com/Slicer/Slicer/issues/5863>

> Cannot download extensions from the Extensions Server when using a regular web b…rowser.

> 
> \- Open this page: https://extensions.slicer.org/catalog/All/30181/win?q=slicerigt
> \- Click the "Download" button -\> the button flashes but nothing happens.
> \- Click on the extension's icon to open the details page.
> \- Click the "Download" button -\> the button flashes but nothing happens.

> \## Expected behavior
> 
> Clicking "Download" should download the extension package.

> \## Environment

Until the problem gets fixed you can go to the [web user interface of the extensions server backend](https://slicer-packages.kitware.com/#collection/5f4474d0e1d8c75dfc70547e/folder/5f4474d0e1d8c75dfc705482) and download the extensions you need from there. Extensions for Slicer Preview Releases are in the “draft” folder.
