I see that Directory.Exists(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) + "\PreviousPhotoStore") == false. If you haven't created the "PreviousPhotoStore" folder, how can you migrate the user data?
Please consider to edit the MSI and the code behind so that data migration. And I created a MSI but nothing successed. The build success but the app didn't run!
