Sqlite3.Open always returns CannotOpen

I am trying to access skype local database using C# and sqlite but my tries always fail Here is the connection code :-

StorageFolder sf =  Windows.Storage.ApplicationData.Current.LocalFolder;
string k = Path.GetDirectoryName(sf.Path);
k = k.Substring(0, k.LastIndexOf('\\'));
k = k + '\\'+ "Microsoft.SkypeApp_kzf8qxf38zg5c" + '\\'+ "LocalState" + '\\' + "goldenwingsonline";
var path = Path.Combine(k, "main.db");
using (var db = new SQLite.SQLiteConnection(path))
{
    string change = string.Empty;
    try
    {

    }
    catch (Exception ex)
    {
    }
}

The code always returns CannotOpen within the sqlite class specifically at this line of code

var r = SQLite3.Open (databasePathAsBytes, out handle, (int) openFlags, IntPtr.Zero);

Although the path is correct but when i try to open it within file-explorer It

Any help please ?
