Issue Details

I had a system running for years until recently there was a Windows update. Now I'm trying to run my LabVIEW code, but I get an error that changes the device every time I try to run it.

Error -201003 occurred at an unidentified location
Possible reason(s):
Device cannot be accessed. Possible causes:
Device is no longer present in the system.
Device is not powered.
Device is powered, but was temporarily without power.
Device and/or chassis driver support may have been removed.
Device is damaged.




My hardware shows up in device manager but in NI MAX, there is a red X next to it. I don't know what is happening.

 

Solution

This problem is most likely caused by the Windows update that caused a corruption either in the database of MAX or in the installation..

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
