The RoboHelp 7 webhelp output is hard coded to check what browser you are using (don’t get me started on this, I hate user agent checks being used to disable functionality). As RH7 predates Chrome, webhelp doesn’t work. Specifically, the Table of Contents (ToC), Index, Glossary and Search does not load.

You can resolve this by editing the whver.js file in the output. The one downside is that this file is regenerated on each build. If you use software to sync the output files to a server you should be able to exclude whver.js from being updated when uploaded new builds.

3 changes to the whver.js file are needed:
