Issue Details

I am using LabVIEW Code Interface Nodes. My Windows Operating System recently became unlicensed and my Code Interface Nodes no longer work. What is happening?


The LabVIEW Code Interface Nodes reference the Windows Core API. When the Windows license became unlicensed, the Windows Core API was made unusable. 
To fix this, re-license your Windows and this will automatically re-link the API to be usable. 

Additional Information

Code Interfaces Nodes are legacy code and NI recommends you switch to using the Call Library Function Node instead.
