C# Check application is installed over Program Files

Hello guys, today I’m gonna show you a code about checking the program is installed or not on Windows system. This program controls all disk name (C:\ , D:\ etc.) and x64-x32 “Program Files” folders.

        static bool ApplicationIsInstalled(string Name)
        {
            var ProgramList = new List {}; 
            var PathList = new List { "Program Files", @"Program Files (x86)" }; //Check x64 and x32 files.

            foreach (var PathName in PathList)
            {
                DriveInfo[] allDrives = DriveInfo.GetDrives(); // Get drive names

                foreach (DriveInfo d in allDrives)
                {
                    string[] subdirs = Directory.GetDirectories(d + PathName)
                                    .Select(Path.GetFileName)
                                    .ToArray(); // Get folder names 

                    foreach (string subDirectoryName in subdirs)
                        ProgramList.Add(subDirectoryName.ToString()); // Add all folder names to list

                    if (ProgramList.Contains(Name)) // Check a folder name
                    {
                        return true;
                    }
                    else
                    {
                        return false;
                    }

                }
            }
            return false;
        }
        static void Main(string[] args)
        {
            if (ApplicationIsInstalled("Google") == true)
            {
                Console.WriteLine("[+] Success! Google is installed on your system.");
            }
            else
            {
                Console.WriteLine("[-] Failed! Google is not installed on your system.");
            }

            Console.ReadLine();
        }
