If you want to create an upgrade that uninstalls the old version and installs the new version, you need to create a major upgrade. A minor upgrade can't do that.
The following technical white papers have instructions and background info on upgrades:
- Download Designing an Update-Friendly MSI Installation
- Building MSI Installer Updates and Patches
For a list of these and other white papers that are available for download, visit the Resources page (http://www.flexerasoftware.com/produ.../resources.htm) on the web site, and then click the White Papers link.
