I’m trying out examples provided in the most recent LabView APIs for MokuLab

Other examples work fine, but in case of Datalogger streaming example, following error messages appear:

As for NI-288.2 driver, it’s installed. After closing the error window, the status code shows mokucli version check: Failed mokucli version check. Requires 2.2.2 or later. Current ver is 2.3.0.

I tried searching for MokuCLI version 2.2.2 but it seems like it’s not available.

Hello,  
I would recommend making sure you have the latest version of the Moku API and mokucli. Start by running:  
pip install moku --upgrade  
This will update your API installation. If you are still running into the same error, try to redownload mokucli from our [Utilities](https://liquidinstruments.com/software/utilities/) page. Please reach out if you are still running into issues!

Hi @zerokelvin ,

Thank you for bringing this to our attention! It might be due to a bug in `mokucli_ver_check.vi`. Could I trouble you to download the modified `.vi` from the Google Drive link below and replace the existing `mokucli_ver_check.vi` in the following directory? Your path may vary slightly depending on where LabVIEW is installed.

“C:\Program Files (x86)\National Instruments\LabVIEW 2016\vi.lib\Liquid Instruments\Liquid Instruments Moku\moku”

> **[mokucli\_ver\_check.vi](https://drive.google.com/file/d/1Oigan-aEvsFU-5s6Qs2Tp0oLZOuKwmAI/view?usp=sharing)**
>
> Google Drive file.

Please let me know if this resolves the issue or if the error persists. Thanks for your patience!

Best,  
Le

I tried Dylan’s suggestion by downloading and reinstalling from the page, and still the same message appears.

I downloaded mokucli\_ver\_check.vi and replaced the file (except that I’m using LabView2017 so I placed in its directory) it seems to work just fine.

Problem solved 🙂

Thank you!
