How to install downloaded updates?

I downloaded some updates from outside KNIME, but I don't think they are installed correctly.

I've got the base package in a subfolder called "\KNIME\knime_2.11.3", which is where I moved the three update folders ("", "org.knime.update.labs", "".

I don't know if this was the right thing to do.

Have a look at on how to correctly install extensions.
