To install the apple driver ( note that this driver fails after sleep, meaning if you put your machine to sleep you won't have use of the trackpad ):
1) Start > Control Panel > Device manager
2) Expand the list of Human Interface Devices
3) Select the USB Human Interface Device second from the bottom of the list (this could vary if you have other usb devices installed)
4) Click the "Update Driver Software" button in the device manager toolbar
5) In the resulting dialog click "browse my computer for driver software"
6) Click "let me pick from a list of device drivers on my computer"
7) If the option for "Apple Trackpad" doesn't show up then you have the wrong device. Apple's driver is unsigned so it will not install by default. If you select it here and finish with the install you'll have two finger scrolling and two finger clicking.
My current work around is using AutoHotKey (
http://www.autohotkey.com). Install the program and add the following line to your AutoHotKey.ini and a command-click becomes a right click (like the good old Warcraft II/Diablo days
):
#LButton::RButton
Alternately for control-click
^LButton::RButton
Hope this helps
