title: Vb.net modify app config connection string during installation
body: <p>I have a small vb.net application using window forms with dataset. Currently the database is stored in <code>c:\</code>. When I created the MSI package and installed on another workstation, I need to change the database location to a network drive <code>z:\</code>, but my connection string in app config is already indicated <code>C:\</code> hence resulted in error. </p>
  
  <p>How can I solve this?</p>
