Hi thitchen007,
It will work with Windows 7 and Vista, you just need the right software. The 7334 uses the NI-Motion software. The latest NI-Motion will work with Windows Vista and Windows 7. These will also work with LabVIEW 2010 and later. You can download the evaluation here: http://www.ni.com/gate/gb/GB_EVALMOTIONASSIS/US
