title: Default uninstall functionality of Setup and Deployment Project can't be executed upon rebuild of setup.exe?
body: <p>I created a setup project to install my application (*.bat file) and successfully installed to end-users' pc. And run the same setup.exe to uninstall the installed application.</p>
  
  <p>Now, I enhanced the application by modifying *.bat file, adding external files, etc..</p>
  
  <p>Then, need to update the setup project to add the newly added external files and things go well and rebuild was done.</p>
  
  <p>The problem is, when I execute the newly rebuild setup.exe on the end-users' pc, uninstall functionality was gone. It only says, old version was installed need to uninstall first via control panel.</p>
  
  <p>Why the uninstall functionality of Setup Project is not longer functioning upon creation of new setup.exe?</p>
  
  <p>Any guidance on the right direction is appreciated.</p>
