UseShellExecute无法找到文件

Question

    public void BuildMod()
    {
        var startIngo = new ProcessStartInfo();
        startIngo.WorkingDirectory = ModBuilderLoc;
        startIngo.FileName = "ModPack Builder.exe";
        startIngo.Arguments = "\"" + 
                 LoadedMod.Directory.Substring(Folders.MyDocuments.Length + 28)
                 + "\"" + " " + "true";
        startIngo.WindowStyle = ProcessWindowStyle.Normal; //TODO: Set to hidden
        //startIngo.UseShellExecute = false;
        //startIngo.RedirectStandardOutput = true;
        try
        {
            Process proc = new Process();
            proc.StartInfo = startIngo;
            proc.Start();
            //proc.StandardOutput.ReadLine();
            proc.WaitForExit();
            MessageBox.Show("Build successful", "Build Info"); 
        }
        catch (Win32Exception)
        {
            MessageBox.Show("Could not find \"ModPack Builder.exe\" in \"" 
                         + ModBuilderLoc +"\", change from menu bar");
        }
    }

这非常合适，除非我取消注释注释，这使得程序读取到程序控制台的第一行。

当注释被取消注释时，会捕获一个Win32异常，我 想要发生这种情况。
