Have you downloaded InDesign CC 2014 from Creative Cloud?
When opened, if it's the latest version, when you choose InDesign > About InDesign (Mac), it should show InDesign CC 2014.1 (NOT 2014). I believe in Windows this is under the Help menu.
If installed, you'll find it in Window > Interactive > EPUB Interactive Preview. It's not under the Object menu. All panels are under the Window menu.
