Hi Mike, Option 1 did not work - I got a message saying: "Failed to find snippet node //SnippetCollection//Language/SnippetDir[last()]"
With option 2 (which was very promising and such a simple solution for me) I get this error in the MSI log. The setup just rolls back immediately: "ExecXmlConfig: Error 0x8007006e: Failed to load value as document." Note: for option 2, I do not have any square brackets or properties that need to be escaped. I even tried it with a very simple one line XML. Thanks!

(http://stackoverflow.com/q/8224918) Also, there are two nodes that match your XPath expression, and XmlConfig only uses the first match. Since you know that the node you have just added will always be the last one (due to the append behavior), you should try this XPath for your 1002 expression instead: ElementPath="//SnippetCollection//Language/SnippetDir[\[]last()[\]]" Notice that you must escape the square brackets per http://msdn.microsoft.com/library/aa368609.aspx I am not certain whether the last() function actually works on XmlConfig, but this should get you closer. If that does not work, then you can try this instead: <util:XmlConfig On="install" Action="create" Id="CreateSnippetDir" Node="document" File="<Path to Xml>\snippetsindex.xml" ElementPath="//SnippetCollection//Language" xmlns:util="http://schemas.microsoft.com/wix/UtilExtension"> <![CDATA[<SnippetDir><OnOff>Off</OnOff><!-- More Stuff --></SnippetDir>]]> </util:XmlConfig> If you use this, it can replace both of your XmlConfig elements, since it combines them into a single operation. Note the Node="document", which lets you specify the XML content to insert, as inner-text of the XmlConfig node. I am not sure whether the Node="document" construct treats the inner-text as a "Formatted String" (http://msdn.microsoft.com/library/aa368609.aspx) or not, so if your "More Stuff" contains any square brackets or [PropertyName] expressions, you may need to experiment to see how it behaves.
