Python node creates Code 1663 in 2020, but not 2023 with same version of Python

[carq]

I have been working on a small VI that I need to work in Labview 2020, but it keeps on throwing Error 1663. I have tried Python 3.6 and Python 3.11. I used the same VI in 2023 Q3 with no errors. Any ideas?

How have you installed Python ? I an virtual environment like anaconda or plain ?

[carq]

I have installed Python directly, and added to PATH. I do have Anaconda installed on my system with Python 3.9.7, but that is not what I am calling in the VI.

Then I don't know. 
Just remember that LabVIEW 2020 only support version 2.7 and 3.6. Higher versions might work. 

Can you show a picture of the error that you get so that we have the complete message.

Please see the attached screenshot.

So what version of Python are you trying to load ? 

What bitnes is the Python version and LabVIEW version ?
