Learn how to diagnose missing module, toolkit, and driver functionality and how to upgrade VIs from LabVIEW 5.1 or earlier.

LabVIEW Can't Open VIs from a Previous Version of LabVIEW

To upgrade a VI from LabVIEW 5.1 or earlier, you must first upgrade to an intermediate version of LabVIEW or use the LabVIEW Conversion Package. Refer to the Upgrade VI to a Newer LabVIEW Version KnowledgeBase article for information about upgrading from your specific legacy version of LabVIEW.

Module or Toolkit Functionality Is Missing

You must install a version of the module or toolkit compatible with your version of LabVIEW. Otherwise, the VIs, project items, dialog boxes, and other features associated with the module or toolkit do not appear in LabVIEW.

• LabVIEW Modules and Toolkits—Download the appropriate version of the add-on from ni.com/downloads.
• Third-party Add-ons (Windows)—From the Getting Started window of LabVIEW, select Find Drivers and Add-ons»Find LabVIEW Add-ons.
• Third-party Add-ons (macOS and Linux)—Access downloads from the LabVIEW Tools Network.

Driver Palettes and VIs Are Missing

LabVIEW can't recognize the device driver if you install LabVIEW or an add-on after installing device drivers. Modify the driver.

Determining Which Versions of NI Software Are Installed

Use Measurement & Automation Explorer or the system tools available on your machine to determine which versions of NI software you have installed, including modules, toolkits, and drivers.
