Teststand - LabVIEW: Problem of Items incorrectly claimed by a library

Hi everyone,

I am puzzle for a few days now trying to solve a incorrect library claim within a LabVIEW project.

 

The project involves Teststand which calls a LabVIEW project to do certain tasks.  I can call individual VIs from the project, but as soon as Teststand tries to load the complete project, it fails with a TSAPI error failing to load "CIntVIServer.dll". We already reinstalled all NI components and ChatGPT thinks, that it is due to a project error in LabVIEW.

Within the LabVIEW project, there a a few network shared variables organized in about 10 libraries (.lvlib files) containing the share variables. I moved the previously working project from one computer to another, and there have been a few dependenciy issues which have now been sorted. The only issues that remain in LabVIEW, is that all the shared variables in the .lvlib files are marked as "Items incorrectly claimed by a library". Apparently, this issue causes Teststand not to be able to load the project.

 

I already tried to create new .lvlib files and move the shared variables in there (suggestion by ChatGPT) but it did not solve the issue. I also searched the complete harddrive for duplicate files, but there is also nothing there. I am a bit puzzled on how to get this error away.

 

Has anybody experienced this before or has an idea of what the hell is going on?

 

We are using LabVIEW and Teststand 2021.

 

Thank you so much for your help!

Florian

It is recommended to use lvlibp's instead of calling VIs/lvproj from TestStand.

We haven't any problems with lvlibp files for years...
