Is it the same OpenOffice here: https://www.openoffice.org/de/downloads/index.html?

If so, why has LiberKey such an old version?

What is better, LibreOffice or OpenOffice? And can one import the settings, tool bars, etc. from OpenOffice to LibreO?

When I try to open OO this message appears:


I have Java 8 Update 73 installed.
