error installing Knime AI extension

Hi,

I am on a new install behind company firewalls so I am trying to install the extensions using the offline Archives, ( 5.3.2). When trying to install the AI extension I receive the following error,

An error occurred while installing the items

session context was:(profile=KNIMEProfile, phase=org.eclipse.equinox.internal.p2.engine.phases.Install, operand=null → [R]org.knime.python.llm.channel.bin.win32.x86_64 5.3.2.v202408261553, action=org.knime.product.p2.actions.ShellExec).

ShellExec command exited non-zero exit value:

Installation of the Python extension failed:

critical libmamba Download error (6) Couldn’t resolve host name [https://conda.anaconda.org/conda-forge/win-64/ca-certificates-2024.8.30-h56e8100_0.conda]

See the files “C:\Program Files\KNIME\plugins\org.knime.python.llm.channel.bin.win32.x86645.3.2.v202408261553\bin\createenv.out” and “C:\Program Files\KNIME\plugins\org.knime.python.llm.channel.bin.win32.x86645.3.2.v202408261553\bin\createenv.err” for details.

The error looks like there is a call to the external Anaconda URL which would be impossible as we do not allow access to the internet.

In Preferences I am pointing the Conda preferences to a local install from a rival software that includes a miniconda3 installation. Is there a way around this limitation ?

thanks
