ps1 cannot be loaded because running scripts is disabled on this system

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

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.

Open powershell in administrative mode
and run the following command



> `Set-ExecutionPolicy RemoteSigned`

open windows powershell in administrator mode and run the following command and its work VOILA!!

> Set-ExecutionPolicy RemoteSigned

Run this code in your powershell or cmd


Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass

The following three steps are used to fix Running Scripts is disabled on this System error

Step1 : To fix this kind of problem, we have to start power shell in administrator mode.

Step2 : Type the following command set-ExecutionPolicy RemoteSigned
Step3: Press Y for your Confirmation.

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

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.

**Open VS Code terminal and run the following script:**

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted

Paste this code in your terminal

(Visual Studio Code terminal or any IDE you are using)

```
Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted
```
Press Enter

Enjoy :)
