Right. The reason I am asking is because in the past we have used InstallShield for our installations. With InstallShield it is possible to make an installation on top of an older installation, without changing the entry in the Add/Remove programs. It is a feature (one of the few) of InstallShield that I really like.
However, I am aware that MSI usually uninstalls first, before installing a new version. I am not adverse to the concept, on the contrary, however I am wondering why it HAS to be this way. I know I can use patches and minor upgrades etc. to side-step the issue of uninstallation. However I don't want to start packaging patches to one version while Having an complete installer for another version. I can accept patches For critical bug fixes, but the next version is rolled out as a complete Installation. The way we are distributing our software does not warrant anything but a single installation script, I do not wish begin juggling major versions, minor versions etc. So, bottom line: Mainly I am asking from a philosophical viewpoint, but also from a practical viewpoint. /Thomas Due -----Original Message----- From: Chad Petersen [mailto:chad.peter...@harlandfs.com] Sent: 4. februar 2009 17:29 To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] auto delete on reinstall Another thing to consider if you don't remove the old version is what does Control Panel Add/Remove Programs look like. If you have multiple entries then I've had customers remove the older ones, sometimes leading to problems in the newer ones. At a minimum it can cause some confusion.

Subject: Re: [WiX-users] auto delete on reinstall Related question: Why should the old version even have to be uninstalled first? Shouldn't it be enough to just install on top of the old version? If so, how would one do that? /Thomas Due -----Original Message----- From: Chad Petersen [mailto:chad.peter...@harlandfs.com] Sent: 3. februar 2009 17:49 To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] auto delete on reinstall I believe you need to change your Product Id="" to use a different GUID than your previous package and also change the version. You might also need to add a Package Id="????????-????-????-????-????????????", but not sure it is required to remove the previous package.
