I am tri booting windows xp pro xp 64 bit and now vista 64 bit. The question is are we going to remain stuck in th dual boot mode or are manufactures going to come out with drivers. Microtek supporrt just confirmed my scanmaker 5700 is not supporrted in 64 xp or vista and is not going to be. Nikon says my cool scanIV is still being thought about they say they are thinking about it. are there any work arounds. any where to turn. thanks

I have yet to get my HP Scanjet 6500C to run in anything but x86.......... I suppose that is a good question for HP though......... among other Scanner/Printer type hardware devices......

i can certianly help out regarding Nikon scanners on X64.
I have a LS-5000 and this was found not to work on Vista x64. nikon did not support 64 bit drivers.
the way round (and this is not an offial route!) is to go to

and download the software which is free. What you need to do is install the nikon scan software but don't specify that you want to install the drivers for any of the scanners it suggest. If you then installvuscan , that will inturn install drivers for a multitude of scanners , hopefully including the one you have. Go inot device driver and for the scanner that does not have a driver installed fo it, install adriver but point to the inf file that vuscan installs. hey presto, the scanner is recognised.
basically just boils down to a an inf file to fix it.
it occasionally fails in that nikon scan occasionslly loses sigh of the scanner but Idespite that I've managed to scan a large number of slides already.
i don;'t know if this works under XP X64 but I reckon the chances are good that it would.

It's probably cheaper in the end, to just get a top-of-the-range colour laser job designed for business not home users, because home scanners and printers almost never get upgraded to the next OS ... and one of the former is same price as three of the latter ...

OCZ brand name springs to mind ...

I was lucky with my Deskjet F340
