How can I bypass the Boot Camp Assistant Windows Support Software download step?

Hello!

I have a pretty abysmal internet connection (0.4 Mbps down) and downloading the Support software is simply not feasible. Estimates vary from 900 minutes to 3000 minutes. Furthermore, the heavy load drops the internet connection sometimes, so I'd have to download from the beginning all over again. In any case, I managed to bribe my friend into using their Mac to download the Windows Support software from their computer, which is also running 10.13.6. We both have Boot Camp Assistant Version 6.1.0. When they transferred the downloaded software to me, I received it as a folder named "WindowsSupport". I read on the internet forums that the Boot Camp Assistant saved its download in /Library/Application Support/Boot Camp Assistant, so I navigated to that folder and dumped my WindowsSupport in there. I tried running Boot Camp Assistant again, but that didn't work, and it still attempted to download the whole thing again. So I got rid of it and grepped /* for WindowsSupport in order to find out where it was temporarily held while downloading. It didn't return anything except for my own copy. So I used fs_usage to see what it was doing (Boot Camp Assistant) and I found out it handed off the download to systemupdated, which did *not* save it in any human readable format. I don't want to have to drive over to my friend's house to download the software again. Any thoughts on this would be appreciated thanks!
