So the issue with getting the magic mouse and wireless keyboard to work… unfortunately is not a nice one.
Basically, Apple’s Bluetooth Drivers are the issue.
There is a solution in place for Windows XP and Vista… but it’s not so pretty in 7. I’ve tried this, and it worked partially… it would die and in and out.
Basically, get Apple’s Bluetooth v1 bluetooth drivers, and then install either a 64 or 32 bit version of a hacked Bluetooth Mouse driver… this will get your mouse working… not the keyboard.
Again, this doesn’t work so well for windows 7. The best answer i can give you is…. don’t use the magic mouse and wireless keyboard…. with windows 7 bootcamp. until apple provides updated drivers… get different keyboard/mouse. sucks.
if you insist on trying :
apple bluetooth driver : http://support.apple.com/kb/DL952
hacked drivers can be found in this tutorial at the bottom : http://uneasysilence.com/archive/2009/11/14588/
again… i tried this solution… and it has mixed results. some people got it working… but the sliding / scrolling function still doesn’t work…. etc…
