InstallAnywhere 2018 – Build 5868

How can I confirm whether this is the original 2018 release or 2018 SP1?

We are investigating because our existing Java 11.0.8/11.0.9 VM Packs work correctly, but VM Packs created with newer Java 11 versions (11.0.22 and 11.0.32) cause the generated installer to terminate during startup.

I see InstallAnywhere 2018 SP1 available in our Product and License Center and understand that SP1 added Java 11 support.

If Build 5868 is the original release, is it safe to install 2018 SP1 over it, or should it be installed separately?

Thanks.
