1. All it's saying is to remove the camera software using the uninstall software procedure.
2. Then remove whatever drivers are being currently used by going to the control panel -> System -> Hardware Tab -> Device Manager and then remove the items associated with the camera.
3. Restart
4. Install the TWAIN driver
5. Then install the camera utility. (It may not work like this since the camera utility may include the TWAIN driver in the software bundle)
Hopefully it should work then
