Problem installing DAQmx 14.1

[DanLL2020]

Hi,

I've recently had to install LabVIEW 2014 64-bit to work on some old software. The software uses DAQmx subVIs but these wouldn't load because I had DAQmx 19.0 installed. I've uninstalled DAQmx 19.0 and tried to install DAQmx 14.1 instead. When I install 14.1 I get a couple of issues.

If I choose a custom install and try to select Application Development Support for LabVIEW 2014, it's greyed out and I can't choose it. Then, when I try start the installation I get the message that it won't install because it's incompatible with products already installed.

I thought this could be because I was using NI-VISA 19.5 so I tried uninstalling this in NI Package Manager and installing 17.5 instead (which should be compatible with LabVIEW 2014). Strangely, after resetting the NI-MAX configuration data and restarting my computer, I can still see NI-VISA 19.5 in the NI-MAX software menu and still can't install DAQmx 14.1.

Does anyone know what other software could be incompatible and preventing DAQmx 14.1 from installing? I have had a proper search of other forum topics but can't find a solution.

Cheers,

Dan

You seem to have mixed way too many incompatible versions of drivers and software and it can be very hard to unweave it piece by piece.  Go nuclear.  My first advice to to create a Virtual Machine to work in for this project and only install the version of LabVIEW and compatible drivers you need.  If that is not possible, the uninstall everything NI and only install LabVIEW 2014, DAQmx 14.1, and any other 14.x drivers you need.

Hi crossrulz,

Thanks for the advice. All these drivers and software have stacked up over the years so now is probably a good time to reinstall anyway. I'll have a go at this and see if it allows me to install DAQmx afterwards.
