I used this solution from
KainAnderson1) Install the Konica Minolta XP software in Win 7.
2) Plug in your DImage Scanner into a USB port and turn it on with the door closed. It may detect and install the original Konica Minolta Driver.
3) Create an empty folder on you harddrive (for instance go to my computer, double click on the c: drive, then right click and create a new folder named newminolta).
4) Open windows notepad and copy the following into it:
; scanners.inf -- Test Vista Minolta Film Drivers
;
;

; manufacturer's driver, go into Device Manager,
; open Imaging devices, then click on the scanner name
; with the right mouse button and choose Uninstall.
