I have two Airport Express units. iTunes does not recognize either one. I have Windows 8.1.

I have two 802.11n Airport express units. One is operating wirelessly. The other is wired. When I open iTunes, neither Airport express is recognized. I open Aiport utility and both units are on line and operating. What do I need to do to get iTunes to recognize the Airports.

I just upgraded to Windows 8.1.
