Here's a (hopefully) helpful post from near the bottom of that page
Read all the way through first. This is incredibly stupid for a mouse install, but you MUST get all of it working. This takes about 12 reboots.
Do NOT install the provided CDROM software. Do NOT plug your mouse in.
Use your current mouse to download the updates from Razer.
Get the updates all set up (extracted to a folder, etc.)
Uninstall your current mouse from hardware devices.
Reboot.
Install Razer software. During installation, you should be required to accept non-M$ drivers. If you’re lucky, you won’t blue-screen.
Reboot.
Choose a USB port that you want the Razer mouse to always be plugged into; according to Razer docs, it will lose the driver if you plug it back and forth from other ports. Then, plug in the Razer mouse. It may *say* Habu found, but it probably isn’t. Open the hardware screen, and find your mouse in the list. If the drivers are there, then skip down below to #14. Otherwise, uninstall it.
Scan for changes; it will re-install. It still probably won’t have the right driver.
Choose the “Update Driver”. Don’t allow it to search; select the driver. It will want you to put in the CD; don’t. Instead, go to
C:\Program Files\Razer\Habu\Driver and choose habu.sys.
You will know things are correct when you are forced to allow an unsigned driver to install. If you’re lucky, it won’t blue screen.
Reboot.
Now install the Firmware update found in the extracted folder. It will install a “Freescale” driver which you can just let it search for itself and find. It should complete OK. You will be prompted at the end to unplug and replug your mouse - make sure you use the same USB Port.
Reboot.
Now in the Habu configuration software it should be 2.0 software and 2.0 firmware. If it’s not, then good luck.
Reminder that changing the Polling Rate requires a reboot; DPI switching does not. I have mine set on 1000 (scans once per millisecond).
