[Solved] Issue with pyclipper after Kicad update to ver.6.0.4

There were already few topics about this however I do not find solution for my issue.
After Kicad update to version 6.0.4 (where old KiCad 5.1.9 still on PC - should I remove it ?), it seems that RF_tools scripts are not working well. I’m trying to run via_fence and get message:

What is interesing, when I try to install this, from command line I get:

c:\Program Files\KiCad\6.0\bin>pip install pyclipper
Requirement already satisfied: pyclipper in c:\users\admin\appdata\local\programs\python\python37-32\lib\site-packages (1.3.0.post2)

However when trying to install from c:\Program Files\KiCad\bin, I get following:

c:\Program Files\KiCad\bin>pip install pyclipper

Maybe the script is recalling wrong path, however where and how to change it ?

Thanks in advance

You have to use the KiCad 6.0 Command Prompt in your start menu

Trying to run pip directly from \bin of KiCad will never work because Python was never meant for embedding in software properly. The KiCad 6.0 Command Prompt setups the environment to trick it.

Great thank you ! It works.
