Hi, New user here and just got a second hand phantom fc40. Plugged in my battery and paired the remote with the drone and the LED on the front flashes yellow. Looked on you tube for a fix. I need to install software and drivers etc. OK popped over to dji.com and downloaded the required files. fired up the phantom. paired with the remote and attached the USB cable. Double clicked the install file for dji driver and get the error in the attached screenshot. OK off to google. I maybe missing the usber.dll. OK download and copy to directory system32\drivers. try again. Same error, OK, reboot, Same error. Try on windows XP (i'm on windows 7) same error. I've tried the "smack it" approach to no avail. has anyone any idea on how to solve this issue. Many thanks in advance for your replies.
