retrieve header and library files?

Hi, 

I have an issue on the GPIB connection for my new power supplies (Keysight N8700A series).

Previously was using old model of power supplies which is obsolete, thus these series of power supplies is the new replacement. 

I have Keysight IO library which is able to detect and connect my existing power supply, I can retrieve my header and library file in keysight folder in my PC but when I change to new power supply, I cannot see any header nor library files. 

I need these files for my Labwindow CVI programming

Anyway to get the files from the folder ?
