There are some processes that you aren't allowed to access even as administrator. You can trap the exception and keep going:

foreach (Process proc in processlist)
{
  try
  {
    Console.WriteLine(proc.MainModule.FileName);
  }
  catch (Win32Exception e)
  {
     Console.WriteLine(proc.ToString() + "  " + e.Message);
  }
}
