Try
C:\Program Files\National Instruments\NI-488.2\Languages\Microsoft C
It is placed there by the NI-488.2 Setup program when you install the
Language Support - Microsoft C/C++ feature.
If you can't find the files, rerun the setup and verify that the correct
features are installed. Look at the attached screenshot.
