如何判断VC++ 2013是否安装

using Microsoft.Win32;
using System;
using System.Diagnostics;

namespace Test
{
    class Program
    {
        static void Main(string[] args)
        {
            var vc2013Name = @"Microsoft Visual C++ 2013 Redistributable (x86)";
            var version = IsInstalledFromRegistry(vc2013Name);
            Debug.WriteLine(version.ToString());
        }

        public static bool IsInstalledFromRegistry(string displayName)
        {
            var registryPath = @"SOFTWAREWOW6432NodeMicrosoftWindowsCurrentVersionUninstall";
            using (RegistryKey key = Registry.LocalMachine.OpenSubKey(registryPath, false))
            {
                foreach (var keyName in key.GetSubKeyNames())
                {
                    if (string.IsNullOrEmpty(keyName))
                    {
                        continue;
                    }
                    using (var subKey = key.OpenSubKey(keyName, false))
                    {
                        if (subKey == null)
                        {
                            continue;
                        }
                        var name = subKey.GetValue("DisplayName");
                        if (name != null && name.ToString().StartsWith(displayName))
                        {

                        }
                    }

            }
