Unfortunately, Live Cycle Designer is not a Free Adobe Product. If you have purchased Volume Licenses for Acrobat Pro XI and the previous versions as Acrobat pro X, you can contact us at Adobe Support to check for a free upgrade to Live Cycle Designer ES4 11.0 or else you will have to purchase a license Live Cycle Designer ES4 11.0.
Why cant Adobe make it easier and send the upgrade to people who paid for that product in acro pro XI? why make the customer hunt you down. frustrating.
