I thought I posted this question previously but don't see it. Recently installed ES4 and Adobe Acrobate XI Pro replacing Acrobat 9.0 Pro. In LifeCycle there is no pdf preview tab and it's greyed out on the menu. I'm running Win7 Pro 64 bit. What do I need to do. LC is 11.0.1. Browsers on my machine are IE11, Firefox and Chrome.
