I was teaching a RoboHelp 6 HTML class recently and came across the following error message when attempting to edit the properties of project topics (it’s an error I had never seen before).
Clicking OK to the message proved lethal (not that there was an alternative). The topic(s) are unceremoniously deleted from the project and thrown into the Recycle Bin. The Project Manager then shows the topic(s) as missing. Ouch! You can fix the immediate problem by removing the poor topic from the Recycle Bin and re-importing the topic back into the project.
But what was causing the problem? Long story short, the training center I was working with had RoboHelp X5 installed prior to class. When the tech installed RoboHelp 6 on every machine, he was prompted to remove the old version of RoboHelp—which he did. However, the old RoboSource version control software was still installed.
I removed the old RoboSource software (via Start > Settings > Control Panel > Add/Remove Programs) and the problem went away for every PC in the room.
The person who installed the new RoboHelp software incorrectly assumed that the installer would remove all components of RoboHelp, including RoboEngine and RoboSource, which is not the case.
The moral to the story: RoboHelp HTML X5 and the new RoboHelp 6 HTML cannot coexist on the same machine. Prior to installing RoboHelp HTML 6, uninstall RoboHelp HTML X5 and all of its supporting software including RoboEngine, RoboSource and RoboPDF.
