Fail to run Altostra CLI commands from Windows PowerShell


Running any alto command results in a following security error:

alto : File C:\Users\WDAGUtilityAccount\AppData\Roaming\npm\alto.ps1 cannot be loaded because running scripts is
disabled on this system. For more information, see about_Execution_Policies at
At line:1 char:1
+ alto --version

+ CategoryInfo : SecurityError: (:) [], PSSecurityException
+ FullyQualifiedErrorId : UnauthorizedAccess


PowerShell's execution policy is a safety feature that controls the conditions under which PowerShell runs scripts.

On Windows, the default execution policy is Restricted, which permits individual commands, but does not allow scripts and prevents running of all script files, including formatting and configuration files (.ps1xml), module script files (.psm1), and PowerShell profiles (.ps1).

For more information please follow this link.


In order to execute alto commands (and other programs downloaded by npm) you must change PowerShell's execution policy so it allows to run scripts.

To do so, please execute the following command:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Force
