Cannot generate PDF; Java not found

[#1]

Hello,

I recently upgraded to RH v20 to take advantage of the PDF generation features that were not in v19. However, I am unable to generate a PDF from my html files. I've tried smaller and larger TOCs, using different settings in the output configuration, creating brand new output formats in case someone was corrupted, etc. I keep getting the same error in the log after it finishes merging the htm files:"Java not found." I already saw that this was an issue for others so I uninstalled the java I had and resinstalled it with x64 version (C:\Program Files\Java\jre1.8.0_261\bin) and I'm still getting the same error. I've got the latest versions of RH and Media Encoder and everything else I can from Creative Cloud installed and am at a loss about what I can do to fix this. 

I don't know if it matters, but I can generate Word and Responsive HMTL 5 outputs fine.

Everything you have said points to the problem genuinely being the Java installation. You could try generating the About RoboHelp sample project as we know that generates fine if the Java installation is correct.

There is no need to set a Java path so I am wondering if you have set something up that is causing a problem.

1. Did you do anything over and above installing it?
2. Try uninstalling it and rebooting before reinstalling.
3. I don't think it's necessary for this by if you haven't installed Update 1, do that.

If the issue is still there after that, I think you will need to go to Adobe Support. techcomm@adobe.com or your local phone number.

Thank you for your reply, Peter. I haven't done anything special in terms of my installation process. I uninstalled my java installation as well as my RH 20 installation and reinistalled both with their default installation directions. I have also updated RH 20 via Creative Cloud as much as I can and am still seeing the issue. I will contact support to see if anything else can be done. Thanks.

Do you also have the problem if you generate a PDF from the About RoboHelp sample project?

Yes, the sample project also fails to generate a PDF

In that case there is either something still wrong with your Java installation or there is something unusual about your PC setup.

If you are in a corporate environment, seek the help of your IT people. Beyond that you need to contact Adobe Support.

I have assumed you are working on a local machine and RoboHelp is installed to the default location.
