The following error code occurs:

“An error occurred while installing the items
session context was:(profile=KNIMEProfile, phase=org.eclipse.equinox.internal.p2.engine.phases.Install, operand=null → [R], action=org.knime.product.p2.actions.ShellExec).
ShellExec command exited non-zero exit value:”

@GrandMasta you will have to install the extensions you want on the machine that is not behind a firewall.
