ok i just cheated and got my scanner working
i reinstalled my scanner the same way you have to see if i can find a quick work round
your problem without the need to remove this and that from the system.
trying to keep things as simple as possible.
no need to uninstall the software if you follow this
first off download the driver listed here.
when thats downloaded and safe on your desktop.
click start control panel,
double click windows firewall.
in the left hand list click turn firewall on and off.
next screen click continue.
click off and then apply or ok
now go back to your desktop.
shut down any anti virus you may be running.
pull out the usb plug for the scanner in the back of the pc.
now plug in the power pack but don't plug in the usb plug.
double click that file you just downloaded.
it will install the usb drivers into vista.
plug the scanner usb cable in when asked
it should now find and install the usb driver for the scanner.
restart the pc.
double click paperport and it should now run.
if by the off chance it still comes up with no usb cable e.t.c don't worry.
go on line ( important )
now click start , control panel , double click system icon.
now in the left hand list at the top click device manager.
click continue when asked.
look down the list for usb scanner.
right click the mouse button on it
then select update driver software.
it will now search online and what you have just installed.
it should find the correct driver and install it.
i know all this must seem almost to much to read and remember so please print it out and read it as you go along.
one of the two ways above will get that scanner working under vista as i just done both as a test.
the imporant parts are.
firewall must be shut down , anti virus software must be shut down.
go online when i ask.
if i need to go the long way round and use the wizard i will but try the above first it should get you out of trouble.
