Access Denied when saving a file, Windows 8 App

i am using this code to add a node to an XmlDocument and then saving it to an existing file, however i keep getting this error message:

Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

The code i am using is this:

            string xml = string.Empty;

        StorageFolder storageFldr = Package.Current.InstalledLocation;
        storageFldr = await storageFldr.GetFolderAsync("Scores");

        StorageFile sf = await storageFldr.GetFileAsync("Scores.xml");
        xml = await FileIO.ReadTextAsync(sf, Windows.Storage.Streams.UnicodeEncoding.Utf8);

        XmlDocument xDoc = new XmlDocument();
        xDoc.LoadXml(xml);

        IXmlNode xNode = xDoc.CreateElement("score");
        xNode.InnerText = "Hello this is a test";

        xDoc.DocumentElement.AppendChild(xNode);

        await xDoc.SaveToFileAsync(sf);

I would appreciate any help.

Thank you all in advance.

I faced the same problem, but this worked for me:

Windows.Storage.StorageFolder sf = await ApplicationData.Current.LocalFolder.CreateFolderAsync("EMP", CreationCollisionOption.OpenIfExists); 
StorageFile st = await sf.CreateFileAsync("Employee.xml", CreationCollisionOption.OpenIfExists); 
await dom.SaveToFileAsync(st);

I don't believe this is possible without your application having elevated privileges (trusted application - with certificate or an OOB app).

You can set your app up as an out of browser application by following this guide.

How to: Configure an Application for Out-of-Browser Support

However this maybe possible by using isolated storage to save - then modify the XML.

see this example XML File with IsolatedStorage
