USB-UIRT in Win10 64 bit - confusion on copying DLLs

I did copy those over, but aren't those just for the codes the USBUIRT sends to the cable box? (I don't have that set up as a source yet for the new system, as it's in use by the old one, so can't easily test at the moment). I'm trying to set up the USBUIRT to receive commands from the Hauppauge remote that currently sends commands for playback, navigating menus, etc.. That seems to be done from the menu I described, according to the manual:

SageTV can directly receive codes from an infrared remote control. Like keystrokes, these infrared codes can be assigned to commands in Detailed Setup by using the option to link an infrared code to a command. See:
Link Infrared/Keystroke to SageTV Command [...]
After choosing a command for key/IR code assignment, SageTV will display instructions for you to press the key or remote button to be assigned to the shown command. Any keyboard input at this point is considered to be a key assignment. You can cancel this process by clicking on the
Cancel button with the mouse.

That's what I was trying without success to accomplish. I'd press the remote button but get no response from Sage. If I press a key to map it to a command, Sage responds as expected.
UPDATE: After the system had been shut down and then restarted today, I tried the exact same thing and it's working as expected. Go figure...
