I have CCP_Installer from '22. I also have CCPSetup from '15. However, not sure that would help as the installer might need to download data from their servers anyway. Not sure if any of these are full functioning applications.

And, yes, it totally sucks. I've still yet to find a viable competing product. I haven't tried Control4 so maybe that is just as good.

In general I feel like world has move on into either HDMI CEC direction. Or simply just having a TV with soundbar and built-in apps. People don't need any remote except TV.

I think people with multiple devices and closet of equipment are becoming niche.
