Attach the VI at generates this error. It would also help to say precisely what version of LabVIEW you are using. Please note that not too readers of this Forum have installed LabVIEW 2022 Q3 (or whatever is the new designation) ...

Could be something corrupt in "<vilib>\express\DAQmx\DAQAssistantConfig\ConfigVIs.llb\Configure DAQmx Assistant.vi"

Could be something corrupt in "C:\ ... \National Instruments\MAX\Assistants\DAQ Assistant\common\supportFiles\ExpressVIsxxx.llb\"

Could be an improper installation of LV or NI-MAX.

Running 2022 Q3 (just installed) and get the same response when pulling in DAQ Assistant. Please update if resolved. Pinging tech support...will do the same.

For anyone new with the same issue on LV2022 Q3, this is a known issue documented here - https://www.ni.com/en-us/support/documentation/bugs/22/labview-2022-q3-known-issues.html

To resolve the issue, in addition to LV2022 you just have to install LV2021 SP1 (no need to activate)

Hello,

Did you manage to solve out this issue. I have exactly the same problem and I cannot download the version 2021 V1 😞

Is that because you don't have an SSP to download the old version?

Alternatively, go to NI Package Manager, and select LV 2021SP1 to install

hello,
I recently downloaded Labview 2023 Q3 and I have the same problem. I already tryed to repair by NI Package Manager and to install 2021 SP1 version but neither of two way is working to solve the problem.
Is there something else i can do?
I know i can use my licence on 3 pc. If i remove and install the software in the same device it will count as a new device installation?

Thanks

I got the same error on Laview 2026 Q2 on windows server 2025.

Do I need to erase the installation and install a previous version or there is some way to correct?

You do not "Erase" a LabVIEW installation -- you "Uninstall" it! Deleting folders, programs, etc. (or, worse, messing with the Registry) can easily render your system unable to install LabVIEW without "fatal" errors.

If I've done this correctly, here is a link to a "Solution" I posted two years ago on how to safely "Uninstall" all National Instruments Software from a PC. It uses Control Panel to invoke NIPM to uninstall all the NI Software that it knows about, then a second pass to get NIPM to uninstall itself, and a third pass to get rid of a few "loose ends" that NIPM doesn't always know about. I recommend not deleting any National Instruments folders, and definitely not trying to mess with the Windows Registry -- that (in my sad experience) only renders the PC unable to install LabVIEW (you have to basically rebuild the whole PC, starting with "Backup everything, Reformat hard drive, reinstall Windows, reinstall everything else, and restore your profile.

This was not my case. This was a new installation in a new machine.

Please do not "hijack" another user's thread, particularly if you have a similarly-named problem ("LabVIEW Code Generation Failed to Execute). You appear to be working on a different installation of LabVIEW (and with a different underlying Operating System), you have shared nothing about the details of your problem (including what the "failure" was, what the "code that caused the failure" did, etc.

Please start a new Thread. In addition to telling us some of the "What's" (like "What OS?", "What Version of LabVIEW", "What went wrong", "What the code looks like" (actual code is best, but very few of the more experienced LabVIEW users on this Forum are using the "Latest Version", so doing a "Save for Previous Version" and specifying, say, LabVIEW 2021, or (I hate to suggest this) attaching a "picture" (.png) of the code that caused the problem, plus any Error Message or other information that you think might help us figure out NI's, or your, "mistake"). Also add some of the "Who's" (like "Who are you, and how much LabVIEW experience do you have). Is there someone local who knows something about computer programming (not necessarily LabVIEW) that you can "explain" what seems to be going on and also explain what you are trying to do?
