Installing DAQmx 21.0 removes DAQ from LabVIEW 2018

[Brett_Percy]

Hi all,

I have a LabVIEW 2018 installation that I use to support some older software.  I also have LabVIEW 2020 and 2021 installed on the same laptop

According to the compatibility table here https://www.ni.com/en/support/documentation/compatibility/16/ni-daqmx-and-labview-compatibility.html DAQmx v21.0 is supposed to be compatible with LabVIEW 2018 as well as 2020 and 2021

When installing DAQmx 21.0, there is no option to install support for LabVIEW 2018 (this is from a Repair in NI Package Manager but the fresh install looks the same)

I have tried removing DAQmx and installing 18.5 which does work with LabVIEW 2018, but not the newer versions.  This works fine in LabVIEW 2018

I then updated DAQmx to v21.0 again, and now DAQ is missing from LabVIEW 2018 completely - so apparently the DAQmx v21.0 installer knows that LabVIEW 2018 is there, at least enough to remove the existing DAQmx folder from 2018's vi.lib

I've tried installing DAQmx via NI Package Manager and also the offline installer, both have the same result

There's a similar issue with LabVIEW 2017 here: https://forums.ni.com/t5/LabVIEW/NI-DAQmx-Driver-support-for-Labview-2017-is-missing/m-p/4368188 which doesn't have a solution

I'm sure this used to work, as I've replaced the SSD in this laptop in the last couple of months and this setup was installed and working prior to the previous SSD failing

Cheers

Brett
