Hi Bob, I guess I'm completely missing how to version files then. I don't find any attributes or child elements of component or file that seem related. I'm not aware of any consistent file-versioning aspect of the windows file systems. Also, I expect a need to version non-files, such as registry entries.
In my current WiX project, shared items are overwritten with older versions and removed without respect for shared dependencies. I'm trying to correct that. I can't find an example of how versioning and sharing files & registry settings is supposed to work. Let's say I have two components: a "Shared File.txt" file and a "Shared Stuff Version Number" registry entry, installed by potentially one, two, or three otherwise independent MSIs. How can I specify that these components are shared and that reference counts(?) ought to be maintained so that installing any one MSI has everything it needs to operate, that a second MSI with an older version of the shared component does not overwrite the existing shared items but does officially depend on the shared components, and that a third MSI with a newer version of the shared items overwrites, maintaining MSI 1 & MSI 2's official dependency on them, AND that the MSIs may be uninstalled in any order, leaving the newest version of the shared items in place until all three MSIs have been uninstalled at which point no items remain. It would be acceptable if shared items had to be rolled back to the next-most recent version upon un-installation of the most-recent version - if that's just how it works. Am I off my rocker? It seems like complicated functionality, but it also seems that this would be a capability of the Windows Installer. Otherwise, what is this file-versioning for and what are reference-counts for? Thanks!
