Issue Details

I want to download the NI RFSA and RFSG drivers for LabVIEW 32 bits. On the download page , I can see that the bitness of the driver is only 64 bits starting with the 19.0 version. Is the 32 bits version of LabVIEW still supported by NI RFSA and RFSG 19.0?


The NI RFSA and RFSG drivers still include support for the 32 bits version of LabVIEW 2016 and above. However, starting with the 19.0 version of the drivers, NI has dropped support for 32 bits operating systems for these drivers, as mentioned on the readme file of the drivers version 19.0.

Additional Information

The bitness of the drivers shown on the download page is meant to inform that the drivers are only supported on 64 bits operating systems. The drivers will not run or install on any unsupported operating systems.
