I've installed the lastest version of InDesign CC on my Mac and it works great. But in my PC the animations, buttons and functions for ePub don't work. I've tried to unistall a hundred times and still not working, even in the ePub preview. It is a problem in the instalation or in my computer? Because everything seems to work, but when I export the buttons don't have functions..
Moving this discussion to the InDesign ePUB forum.
Are you talking about reflowable EPUB or Fixed Layout EPUB. It's the latter that supports what you want.
Make sure you have downloaded the latest version, InDesign CC 2014.1 (released in October 2014).
