Update application with a newer version
Hello,
My requirement is if my application is installed on the PC. I want to upgrade the application with a newer version.
I have just migrated from VS 2008 deployment project, in that if I just changed the product code it would transparently install the newer version.
However, in 2009 Express if I change the product code it installs the newer version and when I go to Control Panel, it lists my application twice.
If I only change the Upgrade code or the Product version, the installer complains that "Another instance of this application is already installed, please go to Control Panel and remove this first" etc.
Can someone please tell me what properties to change in the project so that Windows Installer transparently reinstalls the newer version.

You will also need to create an entry in the 'Upgrade Paths' view. This way, it will perform a major upgrade by removing the previous version.
