IVI.visa could not be found

Question

My computer A prompted a message notifying me that the latest update for the NI driver was available, so I decided to update it. After the update, I noticed that the executable file compiled with Visual Studio 2015 runs successfully on Computer A but encounters errors on Computer B.

Before I updated it , the executable file worked fine on both computers.

To resolve the issue, I also updated the NI driver on Computer B, but it still didn’t work, and the error persisted.

The error massage is as follows:

"Could not load file or assembly 'Ivi.Visa, Version=7.2.0.0, Culture=neutral, PublicKeyToken=a128c98f1d7717c1' or one of its dependencies".

Hello @Rr,

Welcome to Microsoft Q&A forum.

Is Ivi.Visa a 3rd-party assembly from NI? I searched in nuget.org but didn’t find the corresponding packages.

I suggest you search on your machine A, find and locate the assembly Ivi.Visa(version 7.2.0.0). Move(copy, paste) it to the same location on machine B, see if it works.

If you can find this specific assembly, please also try to directly reference this assembly from your project, rebuild the project and test again.

Best Regards,

Tianyu
