Yes. The latest driver update (v1.43.07.50) for the VCR 2 PC adds support for the 64-bit versions of Windows XP and Vista. You can always find the latest drivers for the VCR 2 PC here."

Sorry this is not an offer to instruct on how to download and install their drivers. Only to note that it appears not ready to use unless you get their latest drivers.
