GetAssemblySoftwareVersion null|OPC UA Implementation: Stacks, Tools, and Samples|Forum|OPC Foundation

Hi

We are running the server in a dll which is loaded by LabView, but we get the below error where it seems to try to get the assembly software version for the OpcUa application. Have you seen this before or have any idea how any idea what we could try to solve it? It works when run from visual studio pro (C#) but not when loaded from LabView.
