Have you tried installing say Synaptics drivers instead?
1. Download the correct Synaptics Drivers for your system, but do not install yet.
2. Next download this troubleshooter:
https/support.microsoft.com/en-us/kb/3073930
3. Run the troubleshooter. Click "Next" and then click "Hide updates."
a. If "ASUS - Other hardware - Asus Support Device" is listed, check the box
and press "next" until the troubleshooter is finished. Then proceed to step 7.)
b. If "ASUS - Other hardware - Asus Support Device" isn't listed, proceed to step 4.
4. Now go into "Device Manager" and uninstall the drivers for "Asus Support Device". It should be under "mice".
5. At this point you want to restart your computer. When the computer restarts, Windows will eventually try to re-download and install the drivers. This may not happen right away, sometimes it takes a while. Luckily you should be able to 'disable' the driver from the troubleshooter before that happens.
6. Again run the troubleshooter and the "Asus Support Device" should now pop up as an option. Select it and run through the troubleshooter.
7. If it's still there, uninstall "Asus Support Device" in device manager, under mice. Then return to step 4 and reboot.
8. Now you want to unzip the Synaptics file and run the setup.exe.
9. Once it is done, restart your computer again.
Now your trackpad options should correctly show up in the control panel "Mouse Options", and Windows won't replace the drivers anymore.
