I created a setup project that installs my Windows application using Visual
Studio 2003. Unfortunately each time when I try to reinstall the application
I get a message from Windows Installer "Another version of this product is
already installed. Installation cannot continue. To remove existing product
use Add/Remove Programs". This is very annoying. How can I make it overwrite
previous installation?

In the properties window of your installer(setup project), there is a
property 'RemovePrevious'. set its value to true. Then it will automatically
uninstall the previous version before installing new version.

You also must increment the Version property in the project properties. It
will prompt you change some codes, say yes.

Thank you for your help. I started to change the version number in each
build and it fixed the problem.
