During my first installation, I have selected additionals nodes installation where I picked chemistry and bioinfo packages. But it ran into an error and I don't see any of those nodes available from nodes repository. I tried finding them and reinstalling but can't find them. I even tried reinstalling the whole KNIME but still can't do it.
Any help will be appreciated.

If you go to help > install new software and then click on the small "Available Software sites" link in the upper right, you should quickly be able to see if you have any update sites registered. Can you please do this and then let me know the result?
