Instructions: Unzip, if it pings your antivirus, then make an exclusion inside of windows protection settings and place it inside of that folder that you made an exclusion for (Sounds sketchy, but I think it thinks its a virus because it reads the memory values of Nightfire or something), then run the speedometer and have Nightfire open, if the speedometer isnt showing your speed when you hit enable then run the program as administrator and hit enable. Now go goof around in airfield.
