[WiX-users] Instance transforms with the msi
Hi, I am using instance transforms (msts) to install multiple instances of my base product (msi) on the same machine. Everything works except for one issue: I use an instance identifier property [INSTANCEPROP] that gets set toInstance1, Instance 2,...etc for each instance. I use this property to write registry keys for each instance. For example - HKLM\Software\ESRI\[INSTANCEPROP] is written via the registry table (One record in the registry table to linked to one component). When multiple instances are installed, this key could be repeated multiple times, but they would all be in their own hive HKLM\Software\ESRI\ Instance1 HKLM\Software\ESRI\ Instance2 HKLM\Software\ESRI\ Instance3 Etc Scenario: The base setup and an instance 1 is installed, I uninstall the instance 1. I find that HKLM\Software\ESRI\Instance1 is still left behind on the machine after instance 1 is uninstalled. Is this because the component that includes this registry key is still in the installed state with the base setup? What would be the best way to ensure that the HKLM\Software\ESRI\Instance1 get removed when instance 1 is uninstalled? Should I make multiple components in the msi each with unique conditions for each transform? Or create a custom action that deletes the registry entry for each transform? Thanks!

Re: [WiX-users] Instance transforms with the msi
Are you using the same component GUID for each of these keys? You can't do that... It's breaking the component rules and all kinds of bad things happen when you break the component rules. Each distinct component keypath (the 'main' entry in a component) MUST have a unique component GUID. Each distinct component GUID can only be installed in one place on a given machine (you can't try to install the same GUID to two different keypaths).
