With release 7.2 of LiveCycle, the install-config documentation is now hosted on the Adobe website at http://www.adobe.com/support/documentation/en/livecycle . The product install binaries themselves only contain PDF files that point to the online location of the full document.
As a result of this change, versioning has become an issue, especially when discussing install-config documentation so that everybody is on the same page!
The version info is provided on page 2, at the top left. It will say something like as follows:
© 2006 Adobe Systems Incorporated. All rights reserved.
Adobe® LiveCycle™ 7.2 Installing and Configuring LiveCycle for JBoss® for Microsoft® Windows® and Linux®
Edition 1.2, November 2006
The key information is the Edition and the Date, which in this case is 1.2, Nov 2006.
This only applies to the install-config guides. API reference guides, developer guides, javadocs and other documentation are still shipped with the product binaries.
