The download works for me:
https://github.com/Helly1206/skin.xonflu...engard.zip

If you're going to install offline though you'll need to make sure you also have all the necessary dependencies listed in addon.xml.
And if you're installing online why not just use the repo?

Thanks for the prompt reply.
I am using a download manager and I am getting an error message to that link.
I need to install the skin on multiple boxes, so I don't want to manully add the source to each box.
