well, I should have come here before - so manual workarounds are already passed on.
I still hope you've got some use for my unofficial MSI setup - I find it quite comfortable to have a replacement CD which just works under Vista x64.
Be my guest and grab the setup from: http://www.markusegger.at/
The setup is constructed to work on Windows 2000 or later and Windows Installer 3.1 or later (although Windows 2000/XP users might not need it - but who knows, the setup shall be open to all modern Windows operating systems).
Hope it's of some use and works for you all, too. Your threads sound like I'm in for the same dilemma with the X-Wing Collector Series - sound like another setup task for the future ...
