A subscription is a new, more flexible way to get Acrobat XI Pro software. A subscription gives you ongoing access to the full functionality of Acrobat Pro XI for a low monthly price. You also get access to every upgrade version at no additional charge, as long as your subscription remains active.
The software installs locally on your computer. It's unnecessary to be online to use your Acrobat Pro XI subscription. Access to the Internet is required during installation and licensing of your software and once every 30 days thereafter. The software alerts you when a connection to the Internet is required for a license status check. You have access to the software as long as your subscription is current.
