Trackpoint Keyboard Drivers for Windows 7 64-bit?

[RDKirk]

I'm having no luck at all getting any drivers to load for my Trackpoint keyboards on a desktop PC under Windows 7 64-bit. I have both a PS/2 Thinkpad keyboard and a PS/2 Ultranav keyboard. I've tried the following drivers:

6egy02ww
6hgx47ww
6hgx50ww
7bg586ww
7bg679ww
7bg686ww
tp4v10k

They all act as though they're loading.
I've got a SWTOOLS/UNAV/ 6HGCX50WW/WinWDF/x64 folder
It reports that Synapticsdrivers have been successfully installed...but they aren't.

They don't show up as drivers in Device Manager.

Does anyone know if a TrackPoint driver can be made to run on a desktop under Win-& 64-bit?
