HI, I have a Bootstrapper made with Burn in which I install some prerequisites like NET Framework 4.0, VC Redistributable, and then 2 or more msi packages that install the programs that make the suite that I want to install using Burn.I have seen the documentation about Upgrade of msi package with Major upgrades, Minor upgrades, Small updates made changing or not the Package GUID and the Version of the package.If one of our msi package need to be upgraded and all the other remain unchaged, which is the best way to make the upgrade?I need to make the patch only for the msi packages that need upgrade and reditribute only that?For using the same interface I need to create a new Burn package to reditribute all the upgrade packages?I need to create the burn new exe package and create the patch from the 2 versions of Burn exe package? Is it possible?I have to chage the code or version of the Bundle package? or only modify the package msi to be upgraded? In this guide I have read about maintain the product GUID of the package for making Small and Minor upgrades:http://wix.tramontana.co.hu/tutorial/upgrades-and-modularization But it says that every time we provide a new msi file we need to change Product GUID, so every time I need to rebuild the msi package I have to change this code, As I have an automated build system, at every build I'll have a new product GUID code. I have provided this using Product Id="*" but in this way I have no control on it. Is this the right way? How I could make an upgrade in this scenario?When I have a fixed release, I have the source code on the servers and when I need to make a fix I need to rebuild the msi setup packages before and after the source code fix but in this way the first msi is different from the one that my build server has build and that I have redistributed and need to be upgraded. because the product GUID code is different every time I rebuild the package, even if the code is unchanged. Do you have any suggestion or best practices for Upgrading setup that use Burn? Expecially using source code system and nightly builds of the setup?Thanks. ------------------------------------------------------------------------------ Minimize network downtime and maximize team effectiveness.
