Hi,
when trying to install extensions I get this error:
session context was:(profile=KNIMEProfile, phase=org.eclipse.equinox.internal.p2.engine.phases.Install, operand=null --> [R]ai.redfield.pst.channel.bin.win32.x86_64 0.1.0.202412031535, action=org.knime.product.p2.actions.ShellExec).
ShellExec command exited non-zero exit value:
Installation of the Python extension failed:
error: subprocess-exited-with-error
error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/
note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for libpff-python

See the files "C:\Program Files\knime_5.3.0\plugins\ai.redfield.pst.channel.bin.win32.x86_64_0.1.0.202412031535\bin\create_env.out" and "C:\Program Files\knime_5.3.0\plugins\ai.redfield.pst.channel.bin.win32.x86_64_0.1.0.202412031535\bin\create_env.err" for details.
Please refer to the documentation at https://docs.knime.com/latest/pure_python_node_extensions_guide/index.html#installation_troubleshooting.
If the current system has no or only restricted internet access a special setup for an offline installation is required. See https://docs.knime.com/latest/pure_python_node_extensions_guide/index.html#_offline_installation.
I deliberately did no chose any redfield extension as it is mentioned and it errored out yesterday. Still, I get this error today. I see “PST” being part of the path, so I will retry without the PST extension soon.
Best
