I downloaded the v3.8 update from the ford website, extracted the zip file, then transfered the files to a usb drive. Went into my 2013 EDGE, ran the update, after the screen saying please leave the car running, a window opens and say bad installation file, one or more of the files being installed on your system did not install successufully. Its step 4 out of 8. What do i do?? i did a master reset, twice and nothing seems to work, i tried to install it manually without success.....please help..
