So the SCF tool isn’t up to date. The latest version is supposed to fix that unzip issue. Download it directly from Sketchucation via your browser and install it. Then quit SketchUp and restart it.
If you installed Fredo6’s extensions lately without using the Extension Store, the Extension Store wouldn’t have a record of that latest install. Fredo6’s Check for Updates would, however.
If updating the Sketchucation Extension Store doesn’t fix this, it might be easiest to delete LibFredo6 and the extensions in question and install them fresh.
