If the file is installed as part of your installation you can simply use it's Id as a Property e.g. [#foo.config] if you set Id="foo.config" in it's File element (see -> http://msdn.microsoft.com/en-us/library/aa368609.aspx). Use that Property as the path for either XMLConfig or XMLFile to make your changes to the file.
If it's put on the target machine by some other means & you can locate the file using normal methods such as RegistrySearch (http://wix.sourceforge.net/manual-wix3/wix_xsd_registrysearch.htm), DirectorySearch (http://wix.sourceforge.net/manual-wix3/wix_xsd_directorysearch.htm) or FileSearch (http://wix.sourceforge.net/manual-wix3/wix_xsd_filesearch.htm) then do so to set your Property for XMLConfig/XMLFile. You will need no Custom Actions in either of these cases which should make your code much more resilient. If you can't locate the file using normal methods then a Custom Action which sets a Property containing the path to the file is your only option. How is this file installed on the target system initially? If it's by another product you can usually use a RegistrySearch to find something like the InstallLocation & extrapolate the rest of the path from there. If you're really lucky & the other products authors thought about this ahead of time there may be a standard registry key set by their installer for you to grab the location from. Avoid using Custom Actions unless you have no other option.

Subject: [WiX-users] Editing config files after installation Hello, I suppose this question was asked before, but i couldn't find a clear answer for it: When an installer runs on the target machine, and installs all the files in the InstallDir, i would like to carry some extra actions. -Get a config file that was installed, i.e foo.config. -Modify that file (which is in xml format), by adding some values in the key/value pairs. Now as far as i know from the search i've done, i can only do this after InstallFinalize, because that is when the files are showing in the InstallDir.? What is the ideal way of doing this? i.e: -are there built in wix methods to grab foo.config? -should i use the "util:XmlFile" tag for the editing? -what are the general steps for doing this process? e.g put all the steps in a custom action and call it after InstallFinalize?
