I understand that you are going through problems when trying to install the Intel ® Management Engine.
Regarding this, what I could recommend you to do right now is to manually try to install it by downloading it from the Lenovo* support site. I actually tried looking for the model of your system and I found this link which I hope it helps:

Download the Intel ® Management Engine from the "Chipset" section and attempt to install it, let me know the outcome please.
