I use Sunshine with the Moonlight client for Remote Desktop. With my computer running Tailscale I can connect to it from anywhere. It’s designed for game streaming on a local network, but tweak the bandwidth settings down and it works a treat for remote work.
You could maybe setup a SMB share targeting your download location, mount that on the computer you’d like to install on, then point the setup.exe at the SMB share for the bin files.
