Part of the problem for both Win7 and Win8 has to do with security on the \Program Files (or \Program Files(x86)) folder. For these versions of Windows, processes launched from outside a child folder of \Program Files cannot access files in another child folder of \Program Files. I'm learning the hard way that while setting up a new 64-bit machine, it was a big mistake to accept the setup defaults and install FSX in the \Program Files(x86) folder. Not just EZDok and TrackIR, but also REX had issues. REX team fixed theirs in beta update 3.6.2013.0124 btw.
An experiment with user account control (UAC) confirmed my suspicions. Before turning off UAC in control panel, I couldn't get EZdok 1.15-1.17 to recognize TrackIR5.2.1 at all. With UAC off, EZDok sees TrackIR (EZdok Studio lights up all the TIR options). I still don't have TrackIR controlling pan/zoom alongside EZDok, however.
For those of you having problems, where do you have FSX, EZDok and TrackIR installed?
