Hi,
LabVIEW 6.1 is compatible with Windows XP. The DAQ VIs may be missing
since they are intalled by the DAQ driver. If you do have the driver
installed is just a matter of runnign the NI-DAQ installer again from
Add/Remove programs, select modify and make sure that support for
LabVIEW 6.1 is selected. This should bring the DAQ VIs back up.
let me know if you have any further questions.
Regards,
