WOW! After MANY posts and tries using AIRNAVS Flightstick, I return it for a refund from Amazon. After purchasing FLIGHTAWARES (flightaware.com) flightstick and installing on my current Windows 10 PC, IT WORKS OUT OF THE BOX using the same Airnav's Radarbox software V6.02.003!!! I have the legacy Radarbox black box which worked OK but FLIGHTAWARES product surpasses Airnav's product and works first time!!
I am getting 20-30 percent more received planes now.
Don't try Airnav flightstick, go to Flightaware!!
