RH 2020 - 'Java not found' when generating PDFs

Hi all,

 

Just installed the new RH 2020. Since, it's ran sluggishly - and when generating a PDF, it says ''Java not found' in the log.

 

Is my system's Java out of date?

 

Thanks.

You are showing a link to the Java Development Kit. You required the Java Runtime Environment. 

 

Java SE Runtime Environment 8 - Downloads | Oracle United Kingdom

 

You may required a different link as the above is for the UK but it is the Runtime Environment you need.

RoboHelp itself does not need Java so anything you have there should not affect performance. Did you install to the default location with admin rights?

 

Generating a PDF does require Java. Open the About RoboHelp sample project and look at the PDF Output topic. It's explained there.

Hi Peter. Thank you for your response.

 

I am running the latest version of Java 8 - which is higher than the version specified in the topic:

I will get in touch with technical support.

Please post back when you hear from support! I'm also having the same issue (same version as you, 1.8.0 261). The installer had already added an entry in the system PATH variable (pointing to C:\Program Files (x86)\Common Files\Oracle\Java\javapath) and I tried adding the Java folder (C:\Program Files (x86)\Java\jre1.8.0_261\bin) to JAVA_HOME and JRE_HOME, to cover all bases... no luck.

 

If I check the java version in a cmd, it works.

C:\Users\ioana>java -version
java version "1.8.0_261"
Java(TM) SE Runtime Environment (build 1.8.0_261-b12)
Java HotSpot(TM) Client VM (build 25.261-b12, mixed mode)

My path is also C:\Program Files (x86)\Common Files\Oracle\Java\javapath.

 

It will be interesting to see what Support come up with.

Please install 64bit version of Java 8 and above. Let us know if that resolves the issue.

I confirm that it works after uninstalling the 32-bit version and installing the 64-bit version. Totally a user error problem on my side!

Good news.

 

For anyone else reading this thread, I have been advised that no path is required by RoboHelp to Java.

Please see the other replies in this thread. The most likely reason is that you have installed the wrong version, 32 bit rather than 64 bit or the other way around.

 

Also see this page for full instructions. PDF Output (grainge.org)

Quick update here - I just ran into this same issue (I'm on a Mac fwiw). I followed the suggestions here to install the latest JRE (runtime environment). However I still had the same problem.

Spoke with Adobe Support and they suggested installing the latest JDK (development kit). 

After installing the latest JDK I was able to successfully save PDFs.
