I try to run powershell script from c#.

First i set the ExecutionPolicy to Unrestricted and the script is running now from PowerShell ISE.

Now this is c# my code:

class Program
{
    private static PowerShell ps;
    static void Main(string[] args)
    {
        ps = PowerShell.Create();
        string ps1File = Path.Combine(Environment.CurrentDirectory, "script.ps1");
        ExecuteScript(ps1File);
        Console.ReadLine();
    }

    static void ExecuteScript(string script)
    {
        try
        {
            ps.AddScript(script);
            Collection<PSObject> results = ps.Invoke();
            Console.WriteLine("Output:");
            foreach (var psObject in results)
            {
                Console.WriteLine(psObject);
            }
            Console.WriteLine("Non-terminating errors:");
            foreach (ErrorRecord err in ps.Streams.Error)
            {
                Console.WriteLine(err.ToString());
            }
        }
        catch (RuntimeException ex)
        {
            Console.WriteLine("Terminating error:");
            Console.WriteLine(ex.Message);
        }
    }
}

And the output is:

ps1 cannot be loaded because running scripts is disabled on this system. For more informationm see about_Execution_Policies at http://go.microsoft.com/fwlink/?LinkID=135170.

Have you tried to set the policy scope to Local machine? 'Set-ExecutionPolicy -Scope LocalMachine -ExecutionPolicy Unrestricted'Elva
Run Get-ExecutionPolicy -List and edit your question with the results. This command will show you the different Scope's and their ExecutionPolicy setting.Complected
That doesn't seem to work I'm afraid, but just to be clear, this is NOT at command line level, as I'm able to run on a remote desktop without problems.Baluster

This could be due to the current user having an undefined ExecutionPolicy.

In PowerShell as Administrator, you could try the following:

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted

BTW, this should be executed in Powershell, not windows's cmd.Opossum
@Tom: any security concern after changing this ?, should we set back this to the restricted or more safe value when our change or work is done ?? (reading the current value and set it back to it when work done ?)Trembles
@HDJEMAI, I guess this depends on what context you are running this. Unrestricted means you can run all scripts. Another option to this would be to set the execution policy to RemoteSigned as this will allow Allow local scripts and remote signed scripts but depending on the application and what it is doing this may still throw the same error. I think your approach is valid in terms of security and you could always read what the policy is before hand using Get-ExecutionPloicy. Although this being said the scope is the current user so the risk in my opinion is small. I hope this helps.Hypersonic
"Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted" is working, thanks @tomPurl
I would also vouch for RemoteSigned. Unrestricted could be unnecessary allowing.Coupon

I did not need to start Powershell as Admin to change this, I could be in Powershell with my non-Admin user instead.Ostrander
If you have a particular project running in VSCode, go for this command - Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Scope Process. The plus side of this command is that the execution policy remains in the default state on the system but only changes for a particular process. There isn't any security concern when you use this command.Foretooth

Open powershell in administrative mode and run the following command

Set-ExecutionPolicy RemoteSigned

Freeway answered 8/11, 2019 at 10:50 Comment(6)
This should be accepted answer, as other answers can be insecure and cause problems.Licht
How about? Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned This worked for me and limits the scope to the current user.Conversationalist
@Conversationalist Depends on what you want to achieve with your shell script and the requirement you are working on per say. You can use either of the way if it does the job and does not raise any concerns. It's all depend on project requirements. What worked for you may not work for me or vice versa under some scenarios/ constraint. We all have choice to optimize the solution as per our need.Freeway

If you are using visual studio code:

  1. Open terminal
  2. Run the command: Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted
  3. Then run the command protractor conf.js

This is related to protractor test script execution related and I faced the same issue and it was resolved like this.

  1. close your current command prompt or vs code (terminal)
  2. open PowerShell in Admin mode
  3. run this command inside PowerShell

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted

  1. answer Y or A (if you want to give access to all users)

  2. now open command prompt or vs code or whatever you like to run your project

Another solution is Remove ng.ps1 from the directory C:\Users%username%\AppData\Roaming\npm\ and clearing the npm cache

Mckee answered 21/6, 2020 at 5:28 Comment(2)
I had the same error with a npm module and this is the solution I like best. If you remove the .ps1 file, it will happly use one of the other two scripts (eg. the .cmd on Windows, the one without extension otherwise), and you don't have to change you security configurationIncurrence
Did the same for yarn.ps1, works perfect! ThanksAlar

This is the best way I've been able to fix it

It is as follows:

  1. First, Open PowerShell with Run as Administrator.

  2. Then, run this command in PowerShell

    Set-ExecutionPolicy -ExecutionPolicy RemoteSigned

  3. After that type Y and press Enter.

  4. Reopen or Restart

  5. Done! working well!

The PowerShell execution policy is default set to Restricted. You can change the PowerShell execution policies with Set-ExecutionPolicy cmdlet. To run outside script set policy to RemoteSigned.

PS C:> Set-ExecutionPolicy RemoteSigned Below is the list of four different execution policies in PowerShell

Restricted – No scripts can be run. AllSigned – Only scripts signed by a trusted publisher can be run. RemoteSigned – Downloaded scripts must be signed by a trusted publisher. Unrestricted – All Windows PowerShell scripts can be run.

This one need to be used in every shell:

Set-ExecutionPolicy -Scope Process -ExecutionPolicy RemoteSigned

Regrate answered 12/4, 2023 at 18:7 Comment(1)
This should be the accepted answer (Windows 10 for me - Works). Thanks!Blockbusting

For Windows 11 go to

system settings -> Privacy & Security -> Choose For Developers tile under Security -> Scroll down to Powershell.

enter image description here

By default the checkbox is checked. If you want to set that click Apply and it set the execution policy to Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser. Then checkbox and Apply button get disabled.

If you want to change the policy again, need to run the Powershell as an Administrator and execute the desired policy.

Sometimes you may not able to change the policy based on the scope and it might get below error.

For an example if you are try to set to the default policy using Set-ExecutionPolicy -ExecutionPolicy Restricted -Scope LocalMachine you may get

enter image description here

To fix this you may need to follow fix-windows-powershell-updated-your-execution-policy-successfully, but the setting is overridden by a policy defined at a more specific scope or check answers in here. cannot change the Execution Policy

Let me improve this answer with the visuals. I took 3 steps and fixed this problem.

Step #1. I opened Windows PowerShell in admin mode (on windows searchbar search for Windows PowerShell) > right click choose the option Run as administrator. You will be prompted again just click on OK

enter image description here

Step #2 Run this command Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted

enter image description here

type Y

Step 3: Close the terminal and move back to where you were previsouly running the command and test it. Like in my case I was having a problem when doing sass -- watch as you can see it now works

Just delete this file ng.ps1

   Path is : C:\Users\username\AppData\Roaming\npm\ng.ps1

It works fine for me.

The more secure one should be (typed at an admin Powershell terminal):

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned

Each case needs a thorough analysis to not expose your system to threats.

RemoteSigned

  • The default execution policy for Windows server computers.
  • Scripts can run.
  • Requires a digital signature from a trusted publisher on scripts and configuration files that are downloaded from the internet which includes email and instant messaging programs.
  • Doesn't require digital signatures on scripts that are written on the local computer and not downloaded from the internet.
  • Runs scripts that are downloaded from the internet and not signed, if the scripts are unblocked, such as by using the Unblock-File cmdlet.
  • Risks running unsigned scripts from sources other than the internet and signed scripts that could be malicious.

Default

  • Sets the default execution policy.
  • Restricted for Windows clients.
  • RemoteSigned for Windows servers.

take a look at all policies

In my case, I needed to allow my azurite (Azure Storage Emulator) script to run, I installed it using npm.

Open the windows powershell or cmd and just paste the following command. If it ask for further confirmation just enter YesSet-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned

below should appear

`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 https:/go.microsoft.com/fwlink/?LinkID=135170. Do you want to change the execution policy? [Y] Yes [A] Yes to All [N] No [L] No to All [S] Suspend [?] Help (default is "N"): Yes PS C:\Users\Tessact01>`
