The simplest way to implement a major upgrade is, as you say, put * for product code, keep the upgrade code and increment the product version. Then just add:
<MajorUpgrade DowngradeErrorMessage="Downgrades are not allowed." /> That automatically adds the RemoveExistingProducts action and the appropriate Upgrade table entries and prevents downgrades too. -----Original Message----- From: Robert Lee [mailto:genrobert...@gmail.com] Sent: 30 November 2011 23:12 To: wix-users@lists.sourceforge.net Subject: [WiX-users] Is major update supposed to duplicate the add/removeprograms entry? I would like to develop an installer so that it would NOT force the user to uninstall the application manually prior to installing new version. Just running the new msi should update everything automatically. As far as I understood the wix book, in order to achieve that, I should set product ID in the markup to "*", keep the upgrade code, and increase version number. But when I run the new msi, a new entry is added to add/remove programs. How to prevent that? ----------------------------------------------------------------------------- - All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity, and more.
