Operating System

  • Windows

Issue Details

While running Measurement & Automation Explorer (MAX) I get the following MAX Database Error:
The MAX database exited abnormally. Visit and enter the info code MAXTerminatedServiceError if the problem persists.

I also may not be able to:
  • See my software under the Software tab in NI MAX
  • Use Test Panels on my devices
  • Use DAQ Assistant in LabVIEW
  • See one of my devices in NI MAX
  • Scan for GPIB devices


This behavior may be seen for several reasons. Follow the next steps to solve the problem:
  1. Make sure the NIMAX.exe has fully closed
  • Right-click on the Windows Taskbar and select Task Manager. Click the Processes tab and select NIMAX.exe (or nimxs.exe for older versions of NI MAX). Click End Process and click Yes. On Windows Vista, make sure you check the Show processes from all users option so all processes are visible.
  1. Restart or start NI Configuration Manager and NI Device Loader services
  • To restart the service, the best course of action is to reboot the computer.
  • If you want to start the service manually, go to Control Panel » Administrative Tools » Services. Scroll down to NI Configuration Manager.  Right-click NI Configuration Manager and select Start. Also, restart the NI Device Loader service. For these changes to take effect, close Services and restart MAX. MAX should now operate correctly.
    • If the NI Configuration Manager service is not started, but all of the options to start the service are greyed-out, skip to Step 4.
  • Another option is to right-click on each service and select Properties. You can check to see if the service has been started in the Service status section. If it is not started, select Start.
  1. Modify those services' recovery settings to help avoid the problem in the future
  • Navigate to their Recovery tabs and select Restart the Service from the First failure, Second failure, and Subsequent failures list boxes, as shown in the image below.
  1. Reset the MAX database.  Please see How to Fix or Restore the NI MAX Database File for explanation on how to do this. Note: Resetting your MAX Database will delete all your MAX Settings (Scales, Virtual Channels, etc).
  2. Force reinstall the NI-DAQmx driver.
  3. Repair the NI-DAQmx driver.
  4. If none of this steps solves the problem, contact NI Support for additional help.

Additional Information

This may have been caused by the NI Configuration Manager or NI Device Manager services crashing. These services may also never have started on your machine. Additionally, an unexpected computer shutdown or crash can cause the NI MAX Database to become corrupt and require a reset of the database.
