RoboHelp is no longer a Microsoft Word add in. You should find it in your Windows Start menu. Just click the Start button and type RoboHelp into the field and assuming it's properly installed, you should see a RoboHelp icon on your windows Start menu.
i can't enable Add in to office 2016. How to enable it. it is enabled in office 2010,
I want to use 2016.
please help me.........
I'm not sure where you are talking about enabling an add in. But RoboHelp 10 will know nothing whatsoever about office 2016 because RoboHelp 10 was created a few years before Office 2016.
Perhaps try downloading RoboHelp (2015 Release) and testing?
