DOS and Windows 3.1 Drivers   The Contour Mouse ships with a full featured mouse driver that offers substantial benefits to even the beginner computer user. Its features are simple to use and yet have the ability to reduce keyboard strokes and mouse clicks alike. By clicking the "Download the driver now" option below, you will download a file named cm202.exe, which is the driver for the PS2 Perfit Mouse with Windows 3.1x or MS-DOS. Please review the installation instructions PRIOR to installation. Before installing the Contour Driver, please remove any other aftermarket mouse drivers (included older Contour drivers). Click Start/Settings/Control Panel/Add Remove Programs Look for any reference to any mouse driver software. If you see one, uninstall it before running our SETUP program. Also look for directories on your hard drive that have mouse in the names. Make sure you run the uninstall.exe from these before installing the new driver. For older Contour Drivers there is usually an uninstall on the floppy that came with your mouse or in the /contour directory on your hard drive. Note: if you were using Microsoft Intellimouse configured for left hand mode please revert back to a right hand mode before installing any of these drivers.   Download the driver now   Home | Downloads | Product Info | News | Support | Where to Buy | Contact Us | Contour Store
