Error Loading .NET Assemblies in LabVIEW

LabVIEW 2013 uses .NET 4.0 by default, while later versions of LabVIEW use more recent versions聽of the .NET framework. When loading an assembly targeted to any earlier versions of the .NET Framework, LabVIEW will聽automatically promote the assembly to the later version.

With .NET 4.0,聽a new security model was introduced. This聽new security model automatically grants full trust to locally available assemblies, but not to assemblies obtained from remote sources like the Internet, network locations, or via email. In case LabVIEW tries to access such an assembly's DLL file with missing trust and is thus denied access, LabVIEW will return an error.聽When using any virtualization solution like Parallels Desktop, VMWare Fusion, or Oracle VirtualBox to run Windows inside a virtual machine, the new security model treats the shared directories (e.g. folders that begin with聽/psf聽or聽\\vmware-host\) as remote sources, as these are accessed through a network link. You need to grant assemblies in these directories full trust as well.
