The most common cause of problems after a LabVIEW upgrade or downgrade when using NI-DAQmx is incompatibility between the Operating System (OS), LabVIEW, NI-DAQmx, and the hardware devices and modules being used. When preparing to upgrade or downgrade your version of LabVIEW you’ll need to carefully consider software/driver/hardware compatibility prior to making changes to your system. To properly prepare for changing your version of LabVIEW, perform the following:
Once you have identified and confirmed the correct versions, you can then install LabVIEW and NI-DAQmx. The most common cause of issues with installation is the install order. NI installers are designed for the Application Development Environments (ADEs), like LabVIEW, to be installed first, followed by the drivers and addons, like NI-DAQmx.
Follow these steps:
If you will need to downgrade NI-DAQmx for the new version of LabVIEW, you must uninstall the current version first. You will need to uninstall NI-DAQmx Run-Time, Configuration, and ADE Support items. You can uninstall multiple items at once by Ctrl + clicking on them and choosing “Remove Selected Items”.
Note: if you intend to keep or upgrade your current version of NI-DAQmx, skip this step.
If you have already installed LabVIEW and NI-DAQmx and are experiencing issues, follow these troubleshooting steps.
