.NET configuration file
Follow these steps to allow LabVIEW access to all .NET assembly. Please note that this approach imposes a potential security risk.
With .NET 4.0, a new security model was introduced. This 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: An error occurred trying to load the assembly.Note: This error message may also occur when you attempt to load a 64-bit .NET dll into a 32-bit version of LabVIEW or vice-versa.
Note: 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 /psf or \\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.
