windows 10 / install of sitebuilder desktop / steps and help?

I have a new dell laptop that I need to install the old homestead sitebuilder desktop version on to continue updating some older sites that are too large to move over into the web based without weeks of work.

Where is the download, i can't even find it on the main page of homestead and are there certain steps or things I need to do to make it work properly with windows 10?
