The process of downloading the Saitek Desktop Optical Mouse driver should begin automatically after a few seconds. If this does not occur, click on one of the links below (we recommend downloading the Saitek Desktop Optical Mouse driver from the primary server - this is the manufacturer’s Others official website). If the download still fails to run, check whether your anti-virus software is not blocking the connection to the manufacturer server of the Saitek Desktop Optical Mouse diver.
