Ps command not running under windows service

Question

When trying to run a ps command inside a windows service it returns me an error:

Get-LocalUser : 'Get-LocalUser' not recognized as cmdlet, function, script file or program. Verify if the file path is correct and try again. C:\Users\Admin\source\repos\ps.test\bin\Debug\GetLocalUserv2.ps1:1 caractere:1

• Get-LocalUser

•   + CategoryInfo          : ObjectNotFound: (Get-LocalUser:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException
  
  

But when I run it as a console project it runs ok! Is there any windows limitation running some ps commands inside a win service?

using System.Diagnostics;
using System;
using System.ServiceProcess;
using System.Management.Automation;
using System.Timers;
using System.IO;
using System.Reflection;

                //Logger.Error($"Erro ao executar script {e.Message}");
            }
            File.AppendAllText(logPath, output + Environment.NewLine);
            try
            {
                var test = PowerShell.Create().AddScript("Get-LocalUser").Invoke();
                System.IO.File.AppendAllText(logPath, "test->" + test);

        {

            File.AppendAllText(logPath, "stop->" + DateTime.Now.ToString("yyyyMMdd:HHmmss") + Environment.NewLine);
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            
        }
    }
}

I think I solved the problem. After searching the web there're some ps commands you have to enable x64 in the solution. And the service was 'Any CPU'. After fixing to x64 it worked.
