Hi 1. Is it possible to uninstall just a single instance, if that instance is no longer needed?
Yes, Add/Remove programs will do it, or you can use the command line if you know the Instance ProductCode 2. Is it possible to upgrade just a single instance, if needed. Yes, but again you need some way to identify the instance, especially if it is a major upgrade. With a Major Upgrade, I found that the AppSearch finds all of the instances and schedules them all for deletion. So what I do is write the current product code to a registry key, read it in, and then substitute this value into the Property from the Upgrade table (can't remember the term). There are some other discussions over the past few years in wix-users that discuss other ways of dealing with major upgrades.

Subject: [WiX-users] Multiple instance install questions I have a requirement to add the ability to support multiple instance installs to our website Wix installer. I've been looking at a few sites that discuss how to do this, but I have a couple of questions regarding this. 1. Is it possible to uninstall just a single instance, if that instance is no longer needed? 2. Is it possible to upgrade just a single instance, if needed. We are currently using Wix 3.5 for our web application installer, which is used to install a website. The requirement has now been added that the installer must support multiple instances, so that we can do something like below: ProductWebSite\BrandA ProductWebSite\BrandB ProductWebSite\BrandC ProductWebSite\BrandD ------------------------------------------------------------------------------ EditLive Enterprise is the world's most technically advanced content authoring tool.
