Hello, I'm trying to put together a set of installers for multiple products that share a large collection of non-versioned files.
The shared resources are packaged into a merge module, which is included in the installer for each of the other products. The shared resources should only be installed once on the system. Component reference counting (combined with a component search to ensure the keypath for each component's file is correct) works well for this. -- The ideas is that if I install product A, then product B (different product and upgrade codes, obviously) and then uninstall one of them, the files should still be there. The problem I'm having is that I don't want the shared resources to be downgraded, so if an older version of product A is installed after a newer version of product B, the files stay at the newer version. (The products will work with a newer version than the one they ship with, but not an older.) -- Currently, the installer verifies that the component guid and keypath are the same, but determines that the hash and modification date are different (it doesn't seem to care which is in the future) and so replaces the files with the older version. The files are data files and I can't embed a version resource. I looked into making them companion files of something that is actually versioned, but they are split across a large number of directories and I think I'd have to put a dummy DLL in each one to be the component's keypath to get this to work, which is not something I'd like to do. Using a bundle would probably work for this. I could build the shared resources into their own MSI which would handle the versioning the way I want -- but one of the requirements I have is that the thing should be deployable via GPO. I'd also prefer not to have a separately-uninstallable item for them. Is there a way to achieve what I want? If I could find a way of having MSI only install the files if newer in the package, or artificially versioning the files some somehow it would probably solve my problem but neither of these things seem possible.
