Hi @hadesian , if you click on one of the links to the jars in your post, does it go anywhere (e.g. does the browser attempt to download the jar file) or do you get a page not found, or other error message?
btw Yes you can download the 5.2.5 zip separately from here
https://www.knime.com/downloads
Just unzip to a new location. You’ll need to reinstall extensions, and if you’ve change settings (e.g. to memory) in knime.ini remember to change it there again.
