The currently installed driver for the UMAX VistaScan version 2.40 scanner is not compatible with this version of Microsoft Windows and will be disabled during the upgrade. Windows XP Setup will install a new UMAX DS driver so that your scanner will function correctly after the upgrade is complete. However, Umax might have a newer version of the VistaScan software that runs under Windows XP. For more information about this driver, visit the manufacturer's Web site. For a list of devices supported by this version of Microsoft Windows, see the Microsoft Windows XP Compatibility List at http://www.microsoft.com/isapi/redir.dll?prd=whistler&ar=help&sba=compatible.
