THE PROBLEM - Adobe Reader displays a green bar at the top if it thinks you need to sign the document

Adobe Reader and Acrobat 11.0.3 update and signature field detection

In the Adobe Reader and Acrobat 11.0.03 patch, we introduced the signature field
detection capability which identifies documents that the user may need to sign.
Unfortunately, the signature field detection algorithm is finding some false positives
and displaying the signature field detected message when it should not. We have been
following the discussions on our user forums, and understand the inconvenience it has
caused for some users who encountered falsely identified documents. We do apologize.

Users can quickly hide the message bar that appears for a document by clicking the icon
on the left of the message bar. IT professionals and others familiar with working with
registry settings can follow the instructions provided in the version 11.0.3 release
notes (see below) to disable this message.

We are diligently working on improvements for the signature field detection accuracy. We
are also planning to add the ability for users to turn off the signature detection
message more easily. We hope to bring the improvements to you soon. Stay tuned.

The Fix: Source

EchoSign integration

Acrobat and Reader now intelligently detect if a document may need to be signed.

If the words “Sign” or “Signature” are detected in conjunction with any line, a document
message bar appears with an “Open Sign Pane” button.

Adminstrators can disable this feature by editing the registry and setting

HKLM\SOFTWARE\Policies\Adobe\(product name)\(version)\FeatureLockdown\cServices\bEnableE choSignDetection to 0.

If the entries described are not in the registry:

Create the Key: cServices

Create the Value: bEnableEchoSignDetection DWORD 0

This worked for me as of 9/1/2013 using Reader 11.0.3
