Each instance has a unique Product Code. Also, I was following the guidelines from the Windows installer SDK (On how to author instance transforms). How do I install the same set of files for multiple instances using transforms?
Please advise! Uma- Here is the windows installer sdk topic on this: Authoring Multiple Instances with Instance Transforms To install multiple instances of a product from one Windows(r) Installer package, you need to author a base installation package for the product and an instance transform for each instance to be installed in addition to the base instance. Use the following guidelines when authoring your base package and transforms: *Your setup application can check for the presence of the installer running on a version of the Microsoft(r)Windows Server 2003 family, Windows XP SP1, Windows 2000 SP4 and the Windows Installer 3.0 redistributable. Any of these installer versions (or later) are required to install multiple instances from a single package using a product code-changing transform. * Each instance must have a unique product code and instance identifier. You may define a property in the base package, the value of which can be set to the instance identifier. * To keep the files of each instance isolated, the base package should install files into a directory location that depends on the instance identifier. * To keep the nonfile data of each instance isolated, the base package should collect nonfile data into sets of components for each instance. The appropriate components should then be installed based on conditional statements that depend on the instance identifier. * Author an instance transform for each instance being installed in addition to the base instance. The base package may install its own instance. * The instance transform must change the product code and identifier for each instance. * It is recommended that the product transform also change the product name so that the instance is readily distinguished in Add/Remove Programs through Control Panel. * If the instance transform installs files, they should be installed in a directory that depends on the instance identifier. * All nonfile data, such as registry keys, should include the instance name in their path to prevent collisions. This can be accomplished by using the property whose value is the instance identifier in the path as shown by the following example of a Registry Table. -----Original Message----- From: kelly.le...@milliman.com [mailto:kelly.le...@milliman.com] Sent: Monday, December 07, 2009 2:52 PM To: General discussion for Windows Installer XML toolset. Cc: General discussion for Windows Installer XML toolset. Subject: 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).

Everything works except for one issue: I use an instance identifier property [INSTANCEPROP] that gets set to"Instance1", "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!
