A bit more debugging shows that the shared files get reverted to the old
version. These files were the key paths for their components in both new
and old installers. This leads me to think that the "upgrade" is not
considered such...
Here is an example of an installed file being reset to the old version
in the old and new installers. The old installer is InstallShield so I'm
not sure if IS does something extra or not.
