While trying to downlaod a tethering program i get this fault. "TAP driver installation failed." Ive been back and forth with the developer of the program and have come up with nothing. Ive done some googling and this has been a problem with XP/Vista, but i havent come across anything with 7. i dont know what to do. i know i can completely restore the OS, but would prefer a route less difficult. ANY help would be great!!!! Also, this happened with openvpn and other prograqms during installation.
