  • LabVIEW Datalogging and Supervisory Control Module

Issue Details

I just updated my application from LabVIEW 2014 to LabVIEW 2015 SP1. When I run the application I receive an error that states the NVIORef.dll is missing. How do I fix this? 

Solution

If your application runs within the LabVIEW development environment, you will need to install the newer version of the LabVIEW Datalogging and Supervisory Control (DSC) Module that matches your newer version of LabVIEW. 

If your application runs as a standalone executable,you will need to install the LabVIEW 2015 DSC Run-Time System as they are not backward or forward compatible. 
 

Additional Information

Refer to this link to learn more distributing applications that utilize LabVIEW DSC Module features. 

Upgrading your DSC Module version will not require you to also pay for the new version of the Run-Time System. The DSC run-time license is a one-time purchase per deployment. Please speak to your sales representative when upgrading to include the RTS.
