Se acontecer erro instalando intercept do teclado numérico
"could not write to system32\drivers"

siga passos abaixo pra solucionar problema:
rode comando: intercept /uninstall, mande reiniciar o computador, em seguida tente instalar deverá funcionar

Explicação técnica:
try to run "/uninstall". I think your issue should be something with Windows locking the file, so it can't be overwritten. So, even if "/uninstall" gives an error, reboot, and just after reboot, open an admin command prompt (raw cmd), and try install again.

Above instructions solved it for me
