LabVIEW Communications 4.0 lvanlys.dll Error.

[RobCo]

Hello.

I'm currently using LabVIEW Communications 4.0 Trial version to test on my PC before purchasing it.

However when I tired to run example project, USRP RIO 40 MHz BW Single-Device Streaming, there occurs an error that says "Cannot find or load shared library lvanlys.dll"

How can I solve this problem?

The equipment that I use is as follows.

Processor : AMD threadripper 3960x

RAM : 32GB

OS : Windows 10 64x

USRP-2953R

Thanks a lot.

Hi RobCo,

Can you confirm that the DLL is present at the following location on your system? If it's not, you may have a bad installation (which seems unlikely). 
C:\Program Files\National Instruments\LabVIEW NXG 4.0\Win64\lvanlys.dll

If that file is present, it may be that the evaluation licenses you currently have active don't support the analysis library functions as described here. Make sure your evaluation covers LabVIEW NXG Professional in evaluation mode when you look in the NI License Manager. 

If neither of those get you any further, I'd recommend reaching out to NI Support through the official channels (I.E. Request Support on this page).

Thanks !

I solved this problem by setting an environmental variable. MKL_DEBUG_CPU_TYPE=5

I guess this problem occurs with AMD CPUs.
