Software

  • Measurement and Automation Explorer (MAX)
  • LabVIEW

Driver

  • NI-VISA
  • NI-488.2

Issue Details

After trying to use the Instrument I/O Assistant in LabVIEW, I receive an error saying:

 

Measurement & Automation Explorer or the Instrument I/O Assistant is not installed correctly. Please install these from the LabVIEW Driver CD.

Solution

The Instrument I/O Assistant is installed with LabVIEW, but you may get the above error message if was not installed correctly.

 

In order to repair or install the Instrument I/O Assistant, first make sure that you have installed these drivers:

  • NI-VISA
  • NI-488.2 (necessary only if you are using GPIB)

 

After these drivers are installed, you should uninstall and reinstall the Instrument I/O Assistant from the Device Driver media.  If you do not have the Device Driver media, you can download it from the NI's website. Refer to Uninstall or Repair National Instruments Software or Drivers in Windows. Make sure the Instrument I/O assistant is selected when you install the drivers, as shown below:

If you installed a newer version of LabVIEW but have not yet updated both NI-VISA and NI-488.2, you may download a newer version of these drivers and the installation will add the necessary support.

 

If the above mentioned steps do not repair the Instrument I/O Assistant, try the next few steps:

 

1. Completely uninstall both NI-VISA and NI-488.2.

 

2. Remove dependent products.

3. Reinstall NI-VISA, NI-488.2 and the Instrument I/O Assistant from the latest Device Driver CD or installation file.

 

4. Restart computer.

 

If you're still getting the error message shown above:

 

5. Force reinstall NI-VISA: Fix Corrupt or Non-Working NI Software with Force Reinstall.

 

6. Uninstall all National Instruments' software and force reinstall every dependency.

Additional Information

Do not attempt to install the Instrument I/O Assistant's .msi file alone. It requires other components that are installed from the Driver Installer.

A quick and easy workaround for a broken Instrument I/O Assistant is to use VISA, IVI, or Plug & Play drivers for your instrument.
