Always on the 67% installation process.

@rsalencar maybe you can take a look at this thread. Maybe you try a fresh installation with the latest KNIME version in a fresh folder. Sometimes some pip settings and existing (older) folders seem to confuse the installation process:

Still impossible to install.
Even after fresh Knime installation error persists.

PS: i am in a enterprise environment behind proxy. (all other installations works fine)

@rsalencar my suggestion would still be to take a look at the other thread about how to install a Python based extension when you are behind a firewall.

Due to internal policy i am not able to reproduce that same process.
Btw, in this project i plan to use an internal Azure OpenAI Service (closed LLM model).
With that new information, is there anything else i can do as a workaround?
