There's a Nikon compatibility chart that lists the various WT-1,2,3,4,5,7 along with very specific OS version requirements... In my experience, with Nikon, there's very little leeway in their software version requirements... They're very specific, and if it ain't in their chart, it doesn't work... There are also newer less expensive 3rd party solutions that do more than the Nikon devices do... way less expensive...
