Who said MSN Search does not work in XP x64 Edition?

 
I guess it was me and I was partially wrong.

Not currently support but MSN Desktop Search works on my Windows XP Professional x64 Edition on the Ferrari 4000 (after unauthorized tweaking the LaunchCondition section of the MSI with ORCA) or using msiexec /i <your path goes here>\MsnSearchToolbar.msi NOLEGITCHECK=1 after downloading and locating the MSI file during setup).

Indexer works, even indexing PDFs, ZIP and CHM with the appropriate add-ins from the add-in website.
Most of the UI components like Windows Explorer Deskbar and others do not work. Only searching the desktop via 32-bit IE MSN Search Toolbar works.
