Could not load file or assembly 'NationalInstrument.VisaNs, version=9.0.35.156 or one of its dependencies.

Hi, I am new user to this NI Test Stand.

I am currently doing a project to upgrade Test Stand sequence from Win 7 to Win 11 OS. 

I have installed everything such as drivers and tools that compatible with WIN 11 version based on my checking on NI website. 

However, currently I am having this kind of error: 

"Could not load file or assembly 'NationalInstrument.VisaNs, version=9.0.35.156, culture=neutral, PublicKeyToken=18cbae0f9955702a'

Or one of its dependencies. The system cannot find the file specified."

I have to look for NI VISA version 9, but it is no longer available. I also have tried to downgrade my NI VISA version, but the error still persists. In addition, I also not sure how to read the .dll code since I have tried to open it using visual studio, however, I only managed to get the version details. 

I really appreciate if someone can share any idea about this error and thanks in advanced for the help.

Regards,

Amir
