cant install Usb Driver 11 and other Problems

Hello,
I am currently having Trouble with installing the USB Driver 11 from the codeworks for Android installer. I reinstalled everything but it still doesnt work. However, after installing the Software my Cmd also doesnt work, not even the help command. because of that, a command executed by UE4 when trying to deploy my game on my Android phone does not work. But I would as a unexperienced Person think the main Problem is the Driver.
