First of all, I would encourage you to get acquainted with the resources below: - http://msdn.microsoft.com/en-us/library/aa370579(VS.85).aspx and all descendants - this is essential info about upgrades - http://www.joyofsetup.com/2008/12/30/paying-for-upgrades/ - a great summary from Bob (and comments) - the topic "How To: Implement a Major Upgrade In Your Installer" and "Patch Building" section in wix.chm
Lots of text, I know, but you'd better read and understand it now. Good luck. -- Yan -----Original Message----- From: Jiang, Chunyan (GE Healthcare) [mailto:chunyan.ji...@ge.com] Sent: Monday, August 03, 2009 4:56 PM To: General discussion for Windows Installer XML toolset. Subject: [WiX-users] How to create the installation package,which is able to upgrade Hi Wix-users, I have created the installation package with wix. Now I have a new task that .msi should be upgradable. It means that the newly built .msi should be installed without uninstalling the last version, when some files changed in the package. However, my newly built .msi can not be installed. It will pop up an error message like, the package has been installed. How can I make the .msi to be upgradable?
