NI-845x Driver 19.0 - download link is missing



I need to use a special version of NI-845x Driver - 19.0  or 19.5 (if it was released).


The version 19.0 is not available here -





According to this document however - - the version 19.0 exists and should be available.


Do you guys know, where can I get this specific version? Thank you!

I also could not find a LabVIEW 2019 driver for the NI 845x USB SPI master.  I downloaded the 845x-1800 version, installed it, and it works fine with my LabVIEW 2019 code.  In recent (2-4) years, NI has been releasing Drivers that can work not only with current and older versions of LabVIEW, but with yet-to-be-released versions (not sure how they work this trick, but it seems to work).

Yep, the 18.0 release can be used with LabVIEW 2019 with some tricks and manual copy-paste magic.


It would be nice if NI would comment on this and fix the error on the web-site.

As long as you are not using LabVIEW 2016, I recommend just using the 20.0 version.  According the the readme, the only thing that changed was LabVIEW (added 2020 support and removed 2016 support) and CVI (removed 2013 support).

We have a special case where we need to support both LabVIEW 2016 and LabVIEW 2019 on the same machine, so the 19.0 version is exactly what I want.


I hope NI has this version on their servers but just forgot to publish it.
