Sounds like an strange design. Normally you'd make a major upgrade to remove the old version automatically and replace it with the new one. Any data that needs preserving is probably configuration or user data and should be handled by the application rather than the installer. The normal way to uninstall is via Add/Remove Programs (Programs And Features) but you can make a shortcut as shown in http://robmensching.com/blog/posts/2007/4/27/How-to-create-an-uninstall-short cut-and-pass-all-the
Have you set ARPNOREMOVE ? That would suppress the uninstall string. -----Original Message----- From: Alec Swan [mailto:alecs...@gmail.com] Sent: 23 August 2012 15:22 To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] UnistallString is not written in Software\Microsoft\Windows\CurrentVersion\Uninstall\ registry key We use UninstallString to run the uninstaller when the product is updated in place. So, when the user runs our installer the installer looks for UninstallString reg key and if found the installer asks if user wants to wipe out previous product version's data or try to preserve it and then runs the uninstaller passing user's answer as a command-line parameter. Are we doing this wrong? How else can we find the path to the uninstaller of the product version installed on user's machine?
