Hi @Elekrosch , I’m confused at this being a v1.4.2 download of the Continental nodes, as in my KNIME 5.8 installation, the continental nodes are now v1.5.2. That makes me wonder if your installation site config is correct.
Can you check what download sites you have configured in preferences, e.g. it should look something like this (although I have some additional sites specified)
In the “install extensions” dialog in 5.8.0, the continental extension is now found as “XLS Formatting & Utilities”
There was a previously reported problem in 5.7 with located this, but that should now be resolved.
