I'm kind of suprised with Rob's answer. Can you write an install in WiX that does a minor upgrade of an installer written in IS? Perhaps. It'd have to be very careful coding to keep all the primary keys and components the same and get the media built the same way. I suppose it's technicially possible.
But then you'd end up with the same possibly sloppy authoring that InstallShield did and you'd need to come up with your own update.exe to service it. What would be the advantage of that? What's the ROI? The only value I see in this is a good thought excercise to test your MSI chops. If it was me, I suspect I'd do a complete cleanup / refactoring of the install and major upgrade it. ---------------------------------------- From: "Rob Mensching" <r...@robmensching.com> Sent: Sunday, May 13, 2012 4:42 PM To: "General discussion for Windows Installer XML toolset." <wix-users@lists.sourceforge.net> Subject: Re: [WiX-users] Update from Install Shield With very careful coding, you should be able create a minor upgrade from an InstallShield based MSI.
