Sorry, but yes you need the software for everything. The only way to get software is through a Custom Installer, by buying a remote from them, even then you won't get the software, its up to them to furnish the software with remote.

I received it by answering all the remote URC questions over the years, they offered me employees discount on any remote, of course the software came with it. I don't have permission to gave out software like CI can, so don't ask for it from me.
