If you are using PowerShell, your ExecutionPolicy may be restricted. Check using Get-ExecutionPolicy. To change, run PowerShell as administrator.

PS C:\> Get-ExecutionPolicy
Restricted

PS C:\> Set-ExecutionPolicy RemoteSigned

Execution Policy Change
The execution policy helps protect you from scripts that you do not trust. Changing the execution policy might expose you to the security risks described in the
about_Execution_Policies help topic at http://go.microsoft.com/fwlink/?LinkID=135170. Do you want to change the execution policy?
