DAQ Device Not Listed in MAX But Shows Up in Windows Device Manager

Issue Details

My devices are installing correctly and show up green with no exclamations in the Windows Device Manager but some or all do not show up in Measurement & Automation Explorer (MAX).

Why are my devices not showing up in Devices and Interfaces in MAX?


There are three possible reasons for this behaviour, a driver is not tied to the driver in Windows or needs to be updated, a version of DAQmx that does not include the necessary bridge to NI MAX is installed, or a bad installation or corruption of MAX.


If you have multiple modules and only one (or more) are not populated in MAX, the driver may need to be updated or linked to the device itself. See The Drivers for This Device Are Not Installed for Ni Device in Windows Device Manager to learn how to check/fix drivers.

Also, check the compatibility of the DAQmx Driver Version with the Device by checking the ReadMe of the driver. Update to the latest version of the driver that is compatible with LabVIEW, the Operating System, and the device.


Some versions DAQmx do not include NI MAX or any of the bridge files to MAX, when installed. 
See What Are the Different Subsets of NI-DAQmx? to check which subsets of DAQmx install and work with NI MAX.

If you have a subset of DAQmx that does not install MAX, such as DAQmx Core or DAQmx Runtime, install a version of DAQmx that includes MAX, such as DAQmx Full. 

MAX Corruption

Firstly, follow the steps outlined in What is the Process For Resetting the MAX Database? to see if a corrupt database was the cause of the issue.

If the issue persists after these steps, it is likely you have a bad installation of MAX.  
Therefore, we will uninstall MAX and then reinstall it.

Steps to uninstall MAX:

  1. Open the control panel by selecting Start » Settings » Control Panel

  2. Double-click Add/Remove Programs

  3. Select National Instruments Software and click the Change/Remove button

  4. Select NI Measurement & Automation Explorer from the list of National Instrments software and click the Remove button

  5. When asked if you are sure if you want to remove all components, select Remove All

Steps to reinstall MAX:

MAX is installed when any National Instruments driver is installed.

  1. Uninstall a driver (such as NI-DAQmx, NI-488.2, NI-VISA) on your system by following steps 1-3 from above

  2. Reinstall the current version of the driver which will then also install MAX

Additional Information

For subsets of DAQmx that do not include MAX, they also do not install any bridge files to MAX.
Therefore, MAX is not aware of the DAQmx install and is not properly integrated into existing software even though it may appear that your driver has been successfully installed and is functioning normally.

Some subsets of DAQmx, such as DAQmx Core, are intended for advanced users only. 
With DAQmx core you cannot configure, name, or test devices without custom built applications.
