That isn't an error. It is telling you that the component won't be removed because a different MSI on the computer has also installed that component, so the component is still needed.
It may be from a previous failed upgrade. Can you reproduce this error on a clean virtual machine ? -----Original Message----- From: Rajeshkannan Krishnamoorthy [mailto:rajeshkannan.kr...@gmail.com] Sent: 27 June 2012 11:59 To: wix-users Subject: [WiX-users] Major upgrade not working Hi, I tried to install the major upgrade for my application.
