ASP.NET Process Start PowerShell Script IIS 7.5

Question

All works fine on my dev machine but if deployed to IIS the process doesn't get started. I am starting a powershell script by

    private void RunScript()
    {
        Process process = null;
        try
        {
            int timeout = 1800000;
            var startInfo = new ProcessStartInfo
            {
                FileName = @"powershell.exe",    
                Arguments = string.Format("{0} {1}", "\path\toscript", "myParam"),
                UseShellExecute = false,
                CreateNoWindow = true
            };                   

            process = Process.Start(startInfo);
            process.WaitForExit(timeout);
        }
        finally
        {
            if (!process.HasExited)
            {
                if (process.Responding)
                    process.CloseMainWindow();
                else
                    process.Kill();
            }
            if (process != null)
            {
                process.Close();
                process.Dispose();
            }
        }  
    }

Here's what's configured for the app pool this is running under.

Process Model
->Identity = domain user who is a Domain Admin.
->Load User Profile = True

Web App
Authentication is Windows

What else do I need to configure to so that I can run the Process?

As Start-Automating suggested I eventually ended up doing this:

            using (Runspace runSpace = RunspaceFactory.CreateRunspace())
        {
            try
            {
                runSpace.Open();
                RunspaceInvoke scriptInvoker = new RunspaceInvoke(runSpace);
                scriptInvoker.Invoke("Set-ExecutionPolicy Unrestricted"); 
                using (Pipeline pipeLine = runSpace.CreatePipeline())
                {                        
                    var myCommand = new Command(scriptPath);                           
                    var myParam1 = new CommandParameter("-paramName", "someValue"); 
                    myCommand.Parameters.Add(myParam1);
                    pipeLine.Commands.Add(myCommand);       
                    pipeLine.Commands.Add("Out-String");
                    Collection<PSObject> returnObjects = pipeLine.Invoke();
                    runSpace.Close();

                    return returnObjects;                                              
                }
            }
            finally 
            {
                runSpace.Close();
            }
        }

On the IIS server I executed the following powershell command "Set-ExecutionPolicy RemoteSigned"

It's much better to embed the PowerShell APIs the call the .exe

Here's an old link that will get you a PowerShell runspace embedded in ASP.NET per user:

Check the permissions of the file system where powershell.exe lives.

Also, check the Security Log in the Event Viewer for authentication errors and access violations.

The app pool domain account being used is also member of the Administrators group on the machine. So on C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe the Administrators group has Read, Read & Execute permissions. Is that sufficient rights?
