Issue Details

When running some code in LabVIEW Evaluation that uses VISA Read or VISA Write, I get error -107387202.


Follow these steps to install the required drivers (NI-VISA) and resolve this error. 

1. Install the latest NI-VISA drivers from the driver website.
2. Restart the computer
3. Open and run the VI again. The error message should not appear. If other drivers needed, see: Installation Order for Multiple NI Hardware and Software Products  to ensure the drivers are installed in the correct order.

If you already have NI-VISA installed, check the version of NI-VISA is compatible with your version of LabVIEW:  NI-VISA and LabVIEW Version Compatibility.

Additional Information

The evaluation version of LabVIEW does not install the NI-VISA drivers, but it will install the function palettes for the NI-VISA functions. Therefore we have to download the NI-VISA driver ourselves to use the VISA palette.

If you are experiencing this issue while using a FieldPoint RT controller, please contact National Instruments for technical support.
