Your device's software is compatible with Windows 2000 SP4, Windows XP SP2/SP3, Windows Vista, Windows 7 and MAC OS 10.4, 10.5 and 10.6 with the latest upgrades. I have seen many cases when Windows 8 does not install the device properly. I suggest you manually install it using the Device Manager. Right click the device marked in yellow in the Device Manager section and install the driver manually. Point installation window to the location where you have your software extracted. It's a setup file then you will need to install it in a compatible operating system and then copy the contents of the installation from that system to Windows 8.
