You'll need to check SETUP.STF to see how the files are installed; things installed with the InstallSysFile verb and shown as shared are both version and datetime stamp checked. If the .DLLs are put in place with the CopyFile verb, I don't believe they're checked. This is one reason why I use InstallShield for most of my installation process; MS has not provided us a great deal of information on the command language for the Setup Wizard installs as far as I can tell, and the little I've learned about hacking the STF file has convinced me that InstallShield is easier for me to use. I don't rely on Setup Wizard for anything other than the runtime installation.
