Sitebuilder Desktop Download Available

I have been upgrading my sites over time but have a large legacy site still authored in Sitebuilder. My desktop crashed and I need to reinstall, but the download button here https://www.homestead.com/~site/Scripts_SiteManager/SiteManager.dll?CMD=CMDDownloadPage goes to this http://supportdownloads.homestead.com/SiteBuilderDotNet.zip 404 file not found. Is there still any way to get the zip file? (I'll take the risk of figuring out how/if I can make it work.)
