Unable to load LabVIEW Runtime Assembly. Is LabVIEW or the LabVIEW runtime environment installed?

Hello new user of Keysight Test Automation.
I am trying to create a Labview package.
To do this I must first install the OpenTAP Labview package (LabVIEW version 1.0.0+1ea3c463).
Installation of this package is ok.

After installation, Test Automation is started and it gives the following error message:
“Unable to load LabVIEW Runtime Assembly. Is LabVIEW or the LabVIEW runtime environment installed?”

I have Labview 2024 Q3 (32-bit) on my PC and the corresponding Labview runtime.

What is wrong?

Can someone help me?

Kind regards, Geir

Hi @gkr11 and welcome to the forum!

Did you install the 32bit version of Keysight Test Automation?

Hi :slight_smile:

Yes, I used 32 bit version.

Got it, can you try using this version of the LabView plugin: 1.0.1-alpha.1.2+7d7005b2.LvLoadAdditionalInfo

It should provide some more information about why you were not able to load the DLL.

You can check out the code changes here: Enhance error handling in LabViewTypeDataProvider by rmadsen-ks · Pull Request #48 · opentap/LabVIEW · GitHub

Hi :slight_smile:

  1. I have reinstalled Keysight Test Automation 32-bit.
  2. Login to Test Automation and using : Community license.
  3. Installing Labview plugin (version: Alpha)
  4. Respons: “Unable to load LabVIEW Runtime Assembly. Is LabVIEW or the LabVIEW runtime environment installed?”

Thank you very much for helping me.

Ok, I am not 100% on this, and i dont have a LV license so I cannot try it. However, I expect maybe this is caused by the NationalInstruments.LabVIEW.Interop.dll being located in the GAC folder and it is not getting discovered from that location.

Can you try copying the DLL from probably C:\Windows\Microsoft.NET\assembly\GAC_MSIL or C:\Windows\assembly\GAC_MSIL and into your installation folder (C:\Program Files (x86)\Keysight\Test Automation\) and then check if it works.

Hurray :slight_smile:
You were right.
“NationalInstruments.LabVIEW.Interop.dll” is here on my pc:
“C:\Windows\assembly\GAC_MSIL\NationalInstruments.LabVIEW.Interop\1.6.0.0__daeb5dc76be4e32a”

When I copied this to “C:\Program Files (x86)\Keysight\Test Automation” the error message disappeared.

Then I used the Labview example and made my own copy of the Labview plugin via Labview and it works :+1:

Thank you very much for the great and quick help :grinning_face:
