like i said to everyone, check your both device are in the same network, execute the 3DScontroller.exe as admin or with Compatibility troubleshooter
W10 is not a problem if you are using vJoy 2.0.5 (i'm using W10 Pro and it work).
In Control Panel -> USB Playing Device configuration (really don't know the name of the option in english, i have W10 in spanish) -> Select vJoy and then Properties
Try some buttons, if nothing happen then go to configuration -> calibrate
maybe make it work...
if don't, i don't know what else do x'D
