| No, we don't plan to support Vista 32-bit/64-bit drivers for the AX88172 because the AX88172 was an obsolete product. If you need a USB to LAN solution with Vista driver support, you can consider using the AX88772A, AX88772 or AX88178 which are the successors of the AX88172. All Vista 32-bit and 64-bit drivers of AX88772A, AX88772 and AX88178 are qualified by Microsoft Vista WHQL certification.
