How-to-open-a-Word-document-with-Process-Start

I am trying to move a WL6 script to WL8. It is a very simple script to open a Word file for the symbol clicked. If the file does not exist, this will create a new formatted file. I am not finding "Process". Can someone give me a hand?

CODE:
using WealthLab.Backtest;
using System;
using WealthLab.Core;
using WealthLab.Data;
using WealthLab.Indicators;
using System.Collections.Generic;

using System.Text;
using System.Drawing;
using WealthLab;
using System.Diagnostics;
using System.IO;


namespace WealthScript8 
{
    public class MyStrategy : UserStrategyBase
    {
        //create indicators and other objects here, this is executed prior to the main trading loop
        public override void Initialize(BarHistory bars)
        {
         try
         {
            Process.Start(@"C:\DataBus\Stock Information History\" + bars.Symbol + ".doc");
         }
         catch
         {
            File.Copy(@"C:\DataBus\Stock Information History\AAAAFormat.doc", @"C:\DataBus\Stock Information History\" + bars.Symbol + ".doc");

            Process.Start(@"C:\DataBus\Stock Information History\" + bars.Symbol + ".doc");  
         }
        }

        //execute the strategy rules here, this is executed once for each bar in the backtest history
        public override void Execute(BarHistory bars, int idx)
        {
            if (!HasOpenPosition(bars, PositionType.Long))
            {
                //code your buy conditions here
            }
            else
            {
                //code your sell conditions here
            }
        }

        //declare private variables below

    }
}
