Installation problems behind firewall

Hi,

I am having problems in installing the geospatial extension.

I am behind a (company) firewall, so installing from a local file (TrustedCommunityContributions5.2202403141555.zip ).

I did not find the solution in the forum, so could you help me, please?

(current installation: Knime 5.2.1; other extensions worked).

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]sdl.harvard.geospatial.channel.bin.win32.x86_64 1.2.0.202311151543, action=org.knime.product.p2.actions.ShellExec).

ShellExec command exited non-zero exit value:”
