What is the scanner?
Vuescan supports every scanner I've owned since the mid-90's. I now use it for everything from making a quick copy (direct scan to print) to making very high resolution film scans using a high-end Nikon LS-8000. The oldest scanner it has run for me is an Acer 1240UT (ca. 1998) and the newest is an Epson V750.
See if your scanner is on this list:

And what do you intend to do with a scanner? If it is making copies, then any scanner will work fine. If it is scanning photographs for enlargement, just about any scanner will still work fine if it is being run by good software. If it is scanning film, then that opens up a whole new line of questioning.

Many photographers keep their old-but-good scanners in operation even when their manufacturers don't support newer operating systems. I was able to keep a Minolta Multi II film scanner in operation for years after Minolta stopped supporting it (prior to their disappearance), and would still be able to use it had I not replaced it with the Nikon. The Minolta has a SCSI interface--not a problem, even using a USB-SCSI converter. The Nikon has a firewire interface--not a problem. The Epson has a USB interface--not a problem. Vuescan provides native support for nearly all the supported scanners--you usually don't have to install the manufacturer's driver. And you can download it and test it with your scanner before you have to pay a nickel.
Yup, it also supports both 32- and 64-bit versions of Windows operating systems, including Windows 7.
