Issue Details

I have a .NET based Dynamic Link Library (dll) that is working fine with LabVIEW. However, when I attempt to use the similar .NET dll in LabVIEW 2026 Q1, I am not able to load it successfully. VI will break if I attempt to use LabVIEW 2026 Q1 to open a VI that calls the .NET dll. How to resolve this issue?

Solution

This is caused by a bug in LabVIEW 2026 Q1. To date, there is no solution available for this issue. Customer who experiencing this issue is suggested to use older version of LabVIEW as temporary workaround.
