Installing the Razer Tarantula on a Vista System
Thanks to the unpopular driver signing restrictions on Microsoft Vista, installing a Razer keyboard (such as the Tarantula model) without the correct device driver disc is next to impossible.
Driver signing is a process whereby only approved drivers that don’t impact on the running of the operating system can be installed. While you might expect all drivers to be appropriately signed for use in Windows, this isn’t always the case. This can potentially restrict the selection of available hardware, particularly in a situation like this.
If you have the driver disc that shipped with the keyboard, then you won’t have any problems – but even running the official driver from the Razer Support website will cause problems in Vista if the driver has not been correctly signed.
Without a signed driver you will be unable to install the keyboard on a Vista 32 bit operating system (although this problem does not exist on the 64 bit version). As such, your best solution is to try the most up-to-date version of the driver, v2.10, which has been designed to work correctly with Microsoft Vista 32-bit.
To use this driver, download from the location above, save to your PC and double click to install. If the Razer Tarantula keyboard is not detected, disconnect and then reconnect the USB cable; if there are further problems open Start > right-click Computer > Properties > Device Manager and find the keyboard under Human Interface Devices. Then, right-click and select Update Driver Software, and the operating system should do the rest.
