This should answer your question:

Windows Version Compatibility with LabVIEW

Compatible Versions of Vision Development Module with LabVIEW and LabWindows/CVI
NI-IMAQ, NI-IMAQdx, NI-IMAQ I/O, and VAS Compatibility with Different LabVIEW Versions
NI-DAQ and LabVIEW Version Compatibility (for Windows)

I would still suggest to have a look at the readme files as well.
