Gotta love Windows Vista... installed on XP SP2 and worked fine. I cancelled the installation of all the default CABs as well (just soft reset), I don't think any were too important because I'm running everything smoothly as of now (though I don't use MMS or Bluetooth). Oh, and Live Search is fantastic, what a great tool!

Again, for those who are curious, works great on a Telus PPC-6700.
