VS .NET Setup and Deployment Project

Hi, existing installation created with Visual Studio 2008 Setup and Deployment project requires the user to manually uninstall existing version of the product.
We do not need that dialog asking user to uninstall. We would like to either overwrite existing files or automate uninstall step.
Any ideas? Thanks.

You need to update the Version and ProductCode properties too when you change & rebuild the setup project.

Just set the appropriate properties for your setup project, e.g. DetectNewerInstalledVersion and RemovePreviousVersions.

If you don't have access to the setup project any longer, I suppose you could extract the files from the current installer and re-package them in a new installer.

I have access to the setup project. All properties are set as described above.
However, I am getting another dialog box:
Unable to install because a newer version of this product is already installed.
Thank you for your help.
