Can anyone help? Thanks :)

You can use ProcessStartInfo class to help you I am attaching an example it could help

This example I wrote to help me to generate key file for com and com+ applications

public void GenerateKeyFile(string path)
        {
            string commandLine = " \"C:\\Program Files\\Microsoft Visual Studio 8\\SDK\\v2.0\\Bin\\sn.exe\" -k ";
            ProcessStartInfo PSI = new ProcessStartInfo("cmd.exe");
            PSI.RedirectStandardInput = true;
            PSI.RedirectStandardOutput = true;
            PSI.RedirectStandardError = true;
            PSI.UseShellExecute = false;
            Process p = Process.Start(PSI);
            System.IO.StreamWriter SW = p.StandardInput;
            System.IO.StreamReader SR = p.StandardOutput;
            SW.WriteLine(commandLine + path);
            SW.Close();
        }
