The error message was ( cannot be loaded because the execution of scripts is disabled on this system. Please see "get-help about_signing" for more details )
Can you help me
This seems to be an error of Powershell.
It should work if you just use the CMD instead.
If you want to stick with Powershell, then you can try to disable the restriction with Set-ExecutionPolicy RemoteSigned
(Powershell has to be run as Administrator)
