Well, before we re-hashed pgInstaller to work the way it now does,
thorough testing was undertaken on 2K, XP and 2K3, with and without
various levels of service pack and in all cases we found that the DLL in
the app dir was used over a pre-existing shared one, exactly as
documented by Microsoft. We *had* to be sure that was working correctly,
otherwise 8.1 installs would be using 8.0 DLLs and chaos would have
reigned!

You might not see it on the lists because Magnus and I tend to work via
IM on pgInstaller, but we both do significant testing using VMs running
various builds of Windows. Both of us having MSDN subscriptions make
life so much easier!
