What's the best way to store your files?

Hi,

I have an application that uses a access-database. The database resides in the folder of the application.
And I use this code to access the database:


        private void mainForm_Load(object sender, EventArgs e)
        {
            AppPath = GetAppPath();
            DBConStr = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" + AppPath + @"\DBRoot.mdb";
        }

        public static string GetAppPath()
        {
            string AppPath = "";
            try
            {
                AppPath = Path.GetFullPath(".");
                AppPath = AppPath.Replace(@"\bin\Debug", "");
                AppPath = AppPath.Replace(@"\bin\Release", "");
                if (AppPath.EndsWith(@"\") == false) { AppPath += @"\"; }
            }
            catch (Exception) { throw; }
            return AppPath;
        }

But when i install the application and run it, the data isn't loaded in my application.
But if I run it again but now with the command run as administrator it works.

What can i do about this?
What is the best way to store you files? Because the /bin/debug
folder is gone after the setup.

Who knows the answer and is willing to help me?
