If your using 32 bit I can provide that file, just let me know Thanks. Fabe Attachment 59590
This is an old thread (18 months ago) but maybe it will be worth passing on my experience today.
I have the same scanner and just upgraded to Windows 7 x64 only to find no official driver available.
After a couple of abortive attemps I got the UK 64-bit driver (see link in the quote from thefabe above) to work OK under compatibility mode. It didn't seem to like "Vista" compat so I also ran it under "Vista SP1" and then "Vista SP2". Nothing happened at first but on a reboot there it is, and working fine!
One possible hitch: there are two different formats for the Windows Twain folder and this driver should go in the one spelt "twain_32" in a sub-folder named "CNQ8400", the other one is spelt "Twain32". I don't know the significance of the two spellings - maybe one is Win 7 the other Vista? Either way, check that yours gets into the "twain_32" version.
I hope this might be of use to someone out there.
