The latest version of XJTAG, version 3.1, is built using the .NET 4.0 framework. To use the latest version of the XJRunner Integration assembly within LabVIEW, LabVIEW must first be configured to accept .NET 4.0 assemblies.

To do this, create a text file named LabVIEW.exe.config containing the following text:

<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0.30319"/>

Navigate to the LabVIEW installation directory in Program Files (or Program Files (x86)), and insert the file next to LabVIEW.exe. Restart LabVIEW for the changes to take effect.

If you are upgrading an existing project, you may need to re-link direct references to the XJRunnerIntegration.dll assembly.
