Issue Details

I am trying to call a .NET assembly with the LabVIEW Constructor Node. When I place it down on the Block Diagram, I don't get a list of assemblies I can call:

How do I resolve this?

Solution

The Constructor Node should be populating with native Windows assemblies. This issue could be caused by a variety of reasons:

Security settings are preventing LabVIEW from accessing assemblies. Configure firewall settings to allow NI products, or turn them off.
Versions of .NET are not installed. Follow this article to check that you have versions of .NET installed
The .NET versions are corrupt. You can repair the .NET Framework.
Corrupt LabVIEW installation. You can force reinstall LabVIEW.
