Initially (like some othe posters here) I could not run the scanner because the program screen extended beyond my display. The fix below worked on a Dell Optiplex GX260, BIOS ver A03.
Go to the setup:
1. Choose Integrated Devices (LegacySelect Options) - you will get a popup. Scroll down and
2. Change Onboard Video Buffer from 1MB to 8MB, save and exit.
I hope this helps someone else out too.
Tschüss,
