[StephenGerads]

in teststand my vi works fine with adapter set for LV development

when I configure the LV adapter for runtime, I get fatal error Labview.lib not called from a Labview process

what is going on?

how do I fix it?

Howdy Stephen -

Are you by chance calling a LabVIEW DLL within your LabVIEW VI which is being called from TestStand?  I know this error occurs when a LabVIEW DLL built in a different version of LabVIEW than the selected Run-time Engine.

Here is a KnowledgeBase which references the issue:
KnowledgeBase 203EA3XC: LabVIEW.LIB Error When Calling a LabVIEW DLL Built with VIs That Use Externa...

If this is the case, you will need to open the LabVIEW DLL source VI in the LabVIEW version you are using and rebuild the DLL.

Thanks and have a great day!
