You're saying that the application generates the files, so they are already the property of the app's code so maybe a CA is the better solution rather than trying to hand them over to Windows to deal with. Transferring ownership is often a problem.
Assuming I understand the issue: I would make empty config files part of the install so that Windows Installer owns them. The app then updates them. On an uninstall they would be removed. On an upgrade with RemoveExistingProducts at the end they would be preserved (because of having the same component guids) but not overwritten because of the file overwrite rules. That would be an installer way that wouldn't involve any code except changing the app to update existing files rather than create them, assuming a late REP works for the product upgrade. --------------- Phil Wilson On Thu, Apr 17, 2014 at 9:32 AM, Bryan Wolf <brw...@jackhenry.com> wrote: > You could also schedule the RemoveExistingProducts action later in the > sequence.
