How to retrieve data from setup file ?

Question

Hello Geeks,

I was made a Windows application setup with a local database for one of my clients. Setup is working fine. Now my client wants to add some extra features to that Windows app and gives me a list of new features.

Now, these special features are completed. My client want to all data as in previous application. But, the problem is that if I give new setup to my client then data will be blank because I have a local database so I don't have client data. So How to retrieve data from setup file ?

 

Thanks In Advanced.
