Get with the machine's maker and get them to supply all the drivers and install procedures.
I am running win 8.1 with media centre installed. When I tried to set up the TV tuner I can see the TV running during the set up but when I get to the finish I get the message IR not detected. I have a media centre remote and it works when i press the button and start up media centre. I have been told that I need to intall Virtual IR Blaster Software but when I look for this software the links go no where
