The difference between the two kits, VXI-PCI8012 and VXI-PCI8015, is the version of the software driver which is included. So it is fine to use the hardware from your VXI-PCI8012 kit with Windows XP if you upgrade to the
latest version of the NI-VXI driver (currently version 3.3.1) which supports Windows XP.
As a tip, remember to uninstall any previous NI-VXI driver using Add or Remove Programs before downloading and installing the latest version from our web site.
