Code to copy Database file when Installing Setup (exe) in on client machine

Hi priyajsr,

You need to add a new screen and the user could select path where he wants to save the database file using FolderBrowserDialog.

string currentPath = Environment.CurrentDirectory + @"\Test.accdb";
FolderBrowserDialog fbd = new FolderBrowserDialog();
if (fbd.ShowDialog() == DialogResult.OK)
{
    string pathToCopy = fbd.SelectedPath.ToString();
    System.IO.File.Copy(currentPath, pathToCopy + @"\Test.accdb", true);
}

Then you need to add a new screen and the user will insert the connection string details by himself and path should be the copied path.

For this refer below link.

Adding connection string during installation

Note : The connection string should be in the app.config not directly in the application code.
