Hello everybody i had this error while installing vex net key firmware witch didnt work
it sais error copy oeimnf() - code 5635
Are you using V4? V4, the system that uses VexNet keys, is deprecated and likely won’t be legal in Vex soon enough.
You are using white VEXnet keys, right? The older black keys do not support firmware updating.
You also need to go through a somewhat convoluted process of installing an unsigned driver if you are using Windows 8.1 or Windows 10 to update your VEXnet keys. Have you done that?

No I didn’t do the unsigned driver process 
Alright will try to do that and see what happens thank you a lot
