Cannot load lvanlys.dll in LabVIEW NXG 4.0


Hello all,


I am trying to learn and to fiddle with LabVIEW NXG.

Whenever I try to use any signal processing analysis or control functions, I get the error:

"Cannot find or load shared library lvanlys.dll."

Not with the simplest of VI's nor with the included examples.


I checked and the lvanlys.dll does exist in the location:

C:\Program Files\National Instruments\LabVIEW NXG 4.0\Win64\lvanlys.dll


This is very similar to the topic in:

However, this is a different product, and the solution there (namely, setting an environment variable: MKL_DEBUG_CPU_TYPE=4 or MKL_DEBUG_CPU_TYPE=5) did not work for me.


I am running Windows 10 64-bit on AMD Ryzen 7 3700X 8-core.


Any help is appreciated.

That might be a licensing issues. Depending on the functions that you are using, some Signal Processing function are licensed. Do you have the Professional or Full Development System activated in License Manager?

Hello Frank,


I have the professional version through an academic license. I believe that all packages and installations are available to me.
