Hello spartanman.
I’m not a Series S owner, so I can only offer you my gut feeling on things. I won’t ask you the annoying “are you sure you did this?” questions.
Considering that the S170 came out about the same time as the TR3, I think you have an excellent chance of getting it all to work properly. It appears to be (right click-“Properties”) “Compatibility” related. Don’t rule out running Hotkeys programs “as admin” either. Be sure that “User Account Control” is turned off.
Regarding Sony’s support of Windows 7 on these older models, I would be very surprised if they make any effort to update drivers for Windows 7. I give it a 0.01% chance. I hope I’m wrong, but I see very little chance.
Good luck and best regards.
