Java? How do I make RoboHelp publish to PDF?

[FrameMaker-dk]

I am trying to publish a PDF from RoboHelp  Version 2022.0.346, but it seems it needs Java 1.8(64-bit) to work.

But I find this java stuff pretty confusing. Apparently the latest java version  21. And Java 1.8 is supposedly version 8. Which is still a far cry from version 21?

I can download the Java file - but what am I supposed to do with it?

Considering this is a program for creating Help files, I believe I would expect something more helpful than this text from the System Requirements:

Trying the, poorly spelled, second option for installing the JAVA HOME environment led me to dialogue where the option for a Java Home Path did not exist?

There are two different Javas - one for running applications and one for developers. The one you want is the user one (JRE = java runtime environment). This is version 8 right now (or 1.8 - blame Oracle for this weirdness). The developer one (JDK - java development environment) is at 21. 

If you search for java using google, the first link will take you to the main java page and the first download button will be for version 8 64-bit. You download it and run the installation file to install java.

You shouldn't need to do anything else, normally. If, for some reason, the environment variable was not set, that is when you need to follow the note. If you use the Robohelp option, you browse to the folder where you installed java (this would normally be in your Program Files folder).

I would suggest uninstalling java, hopefully this will unset any environment variables. Although if you tried to set on in RH you might need to manually delete this. Hopefully you can just delete the value in RH and it will do the rest for you. Otherwise, I recommend getting your IT support to help you.

Then download the JRE 8 version as I mention above and install. Hopefully everything will be set correctly then.
