Work with RoboHelp 2017 Projects in RoboHelp 2015

RoboHelp 2017 projects can be opened in RoboHelp 2015 and worked on. There is just one area to be careful with, HTML5 outputs.

If you need to work on the same project in both versions

• The new Indigo and Ocean layouts can only be added in RoboHelp 2017 and the safest option is to only edit and generate them in that version. If such a project is later opened in RoboHelp 2015, whilst you can generate the output, it will not work correctly. Changes can be made in the RoboHelp 2015 editor but again not all will take.
• With other HTML5 layouts, it depends on the version of RoboHelp in which you added the layout.
  • If the layout was added in RoboHelp 2015, you can generate from RoboHelp 2015 or 2017.
  • If the layout was added in RoboHelp 2017, it's the same as for the Indigo and Ocean layouts, don't work on the layouts or generate them in RoboHelp 2015.
• If you accidentally generate from RoboHelp 2015, open the project again in RoboHelp 2017 and generate from there.

 In short 

• If you select an HTML5 layout in a RoboHelp 2017 output, you must generate from RoboHelp 2017.
• If you need to work using both versions, the best advice to avoid releasing an incorrectly functioning output is not to do anything with the layout in RoboHelp 2015.

To permanently work in RoboHelp 2015 on a project created in RoboHelp 2017

You can only edit and generate HTML5 layouts that were created in RoboHelp 2015. If your project contains any layouts created in RoboHelp 2017, you must delete them (or at least not use them) and add new layouts in RoboHelp 2015. That will mean you will not be able to select the Indigo and Ocean layouts.
