The U.S.A. Microtek Web support site is not kept up to date with the Taiwan Microtek Web site.
Microtek ScanWizard 5 version 6.61 is available for download at the Taiwan Microtek Web site.
It is stated that these drivers are compatible with both 32-bit and 64-bit versions of Windows XP and Vista.
My Microtek ScanMaker i700 is located out-of-state at the moment so I have not been able to test these drivers.
