Strange, it launches in ordinary way, no attempts to update anything, no effect whatsoever (game is added to DrWeb exlusions, just for sake). Tried both launcher.exe and dcs_updater.exe
The same issue for me - trackir works only in zoom in/out modes. Mouse look doesn't work as well. But, at the same time everything works well in 1.2.7 beta version (that I luckily haven't removed yet). Exporting/importing control profiles between the two clients doesn't work (trackir on/off no - help). Any solutions?
P.S. here is thd cfg file I use: https://www.dropbox.com/s/qkpcig89urcv15x/SU-25T%20profile.lua
