Retina MacBook Pro Trackpad in Windows 8

Hello, and apologies if this has been answered anywhere, I've been digging for hours and to no avail.

I just recently picked up the new Retina MacBook Pro, and I'm having issues with the trackpad in boot camped Windows 8. For reference, the trackpad worked fine in Windows 7, and I used the same Windows Support drivers that Boot Camp downloaded for both Windows 7 and Windows 8.

The issue manifests itself as such:

• Windows receives no input from Trackpad at all
• 2 "Touchpads" appear in Device Manager in Windows 8
• Both touchpads have yellow yield sign indicating on further inspection "driver installed improperly"

So far I've tried the following:

• Uninstall and re-scan for devices
• Reinstall by running repair with boot camp utility
• Older versions of the driver in boot camp
• Running the individual boot camp driver directly (results in "you need to run 64 bit version of DPInst.exe"
• Extracting boot camp driver archive, replacing DPInst.exe with a 64 bit version, running DPInst.exe as well as re-archiving and running the driver
• Checking online for additional drivers, including Microsoft's auto-check functionality

Each of these methods have resulted in the same thing, 2 touchpads appearing with "incorrectly installed drivers." I'm at a total loss, if anyone has had any success conquering this issue, or if you've simply been able to use your Trackpad on your RMBP, please share your steps!

Cheers.
