Tryit sorry to say but the drivers do not appear on that page, if you scroll down and read the driver details it clearly states that the drivers on this page are for Windows XP, when you select the vista/vista x64 drivers tab at the top of the page, it states that there are no drivers for this system.

Yes. For Both Vista and Vista 64 bit.
Go to www.xerox.com, On the front page, click on the support and drivers tab.
When that screen opens, in the search box, type DC12.
When that page appears click drivers and downloads from any of the selections that appear. You can select the vista or vista 64 bit driver there, and download the one you need.
