I have been fiddling around the whole evening now, but I cant get it to work on W7 x64 and DCS Black Shark. Runnig FTNIR as admin, uninstalled anti-virus, double checked location of dll. But the C:\FTNoIR_ED_HeadTrackerLog.txt just doesnt appear, and facetracking just doesn't work.
I am running an older version of DCS:BS, to run the training missions. Could that be a problem?
