Web Interaction nodes installation issue

Hi there,

I am trying to install the new Webinteraction nodes (Labs) in KNIME 5.1 and I get 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.web.channel.bin.win32.x86_64 5.1.2.202310191500, action=org.knime.product.p2.actions.ShellExec).

ShellExec command exited non-zero exit value:

Could you give me please some advise what that error might be causing under Windows 10? I am using the local update sites as zip as my source.

Thank you!

Lars
