This page covers some issues that you may experience when running the PowerShell scripts.

Not digitally signed / Unauthorized Access

UnauthorizedAccess error — Not digitally signed error

To bypass this error, run the scripts using the following command from the folder where the scripts are located:

PowerShell.exe -ExecutionPolicy Bypass -File .\walls.ps1

Note: The Bypass command only affects running the specified script. It does not change the settings for any other scripts or alter your PowerShell configuraiton

Script Warning

You may see the following message when attempting to run the script:

Security warning
Run only scripts that you trust. While scripts from the internet can be useful, this script can potentially harm your computer. If you trust this script, use the Unblock-File cmdlet to allow the script to run without this warning message. Do you want to run C:\foo.ps1?
[D] Do not run [R] Run once [S] Suspend [?] Help (default is "D"):

There are several ways to resolve this problem:

Press R to run the script (You will need to do this every time you run the script)
Run the following command instead to bypass the issue

PowerShell.exe -ExecutionPolicy Bypass -File .\walls.ps1

Unblock the file in Explorer. In Windows Explorer, right-click the walls.ps1 file, select Properties, and click the Unblock button.
