Why are my PowerShell scripts not running?

Question

I wrote a simple batch file as a PowerShell script, and I am getting errors when they run.

It\'s in a scripts directory in my path. This is the error I get:

Answer 1

Use:

Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope Process

Always use the above command to enable to executing PowerShell in the current session.

Answer 2

You need to run Set-ExecutionPolicy:

Set-ExecutionPolicy Restricted <-- Will not allow any powershell scripts to run.  Only individual commands may be run.

Set-ExecutionPolicy AllSigned <-- Will allow signed powershell scripts to run.

Set-ExecutionPolicy RemoteSigned <-- Allows unsigned local script and signed remote powershell scripts to run.

Set-ExecutionPolicy Unrestricted <-- Will allow unsigned powershell scripts to run.  Warns before running downloaded scripts.

Set-ExecutionPolicy Bypass <-- Nothing is blocked and there are no warnings or prompts.

Answer 3

Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope Process

The above command worked for me even when the following error happens:

Access to the registry key 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell' is denied.
