Hello, NI-SPY is installed with NI-488.2, NI-CAN, and NI-VISA. There is however a known issue where if you install NI-VISA 3.1, the first time you run the installer NI-SPY doesn't get installed, but if you run the installer again it will install NI-SPY.
Hope this helps! Regards, Steven B. Applications Engineering National Instruments
