The appplication was unable to start correctly (0xC0000142). Click OK to close the application

I have been getting this error while trying to execute a command prompt in C#. I have an app that is supposed to shut down a PC when a user is logged off but I need it to cancel the shutdown when the user logs back on again.

Example:

1. User logs off at 8:30, so I have code in my app to detect this user log off and I use ProcessStartInfo to execute ProcessStartInfo and give it a command to shutdown the PC at a given time (this time is taken from a database and it changes periodically (ie "psshutdown.exe -v 0 -s -t 08:37 ").
2. However if the user logs back on before 08:37 I don't want the shutdown to be executed and neither do I want the user to have to cancel it themselves.
3. To get around this I put in another ProcessStartInfo that aborts the shutdown when a user logs on (psshutdown.exe /a)

However when the code executes the psshutdown.exe when a user logs off, it gives me the following error:

The appplication was unable to start correctly (0xC0000142). Click OK to close the application

It is unable to start psshutdown.exe.

The code that is giving the error is as follows:

 

          //code below takes the time from the database and calcualts the minutes from the current time     

TimeSpan mins = TaskDateTime.TimeOfDay.Subtract(DateTime.Now.TimeOfDay);

//this string is to tell the psshutdown.exe to shutdown the PC after this number of minutes


 string argu = " -v 0 -s -t " + mins.TotalSeconds.ToString();

//code below gets the current directory because that is where psshutdown.exe is installed
string dir = AppDomain.CurrentDomain.BaseDirectory.ToString();


//adds "psshutdown.exe" to the directory
dir = dir + "psshutdown.exe";


//processStartInfo is passed the psshutdown exe directory and the argument
ProcessStartInfo startinf = new ProcessStartInfo(dir, argu);



startinf.Verb = "runas";
startinf.RedirectStandardOutput = true;
startinf.CreateNoWindow = true;
startinf.UseShellExecute = false;
p.StartInfo = startinf;
p.Start();

try
{
p.WaitForExit(10000);



}
catch (Exception u)
{
System.Windows.Forms.MessageBox.Show(u.ToString());

}

I think it is maybe because psshutdown does not have the time to execute. I have tried a timer delay but it didn't work.
