How to Fix Custom Exhibit Stamp Not Working in Acrobat XI
Question details
The user needs to fix a custom legal exhibit stamp in Acrobat XI that cannot be edited after it is applied to a document.

- Product
- Adobe Acrobat XI
- Device & OS
- not provided
- Scenario
- Applying a custom legal exhibit stamp to a PDF document.
- Observed behavior
- The custom exhibit stamp is successfully installed in the Stamps folder, but its name and content remain locked and cannot be edited after placement.
Ensure you have the original download package from the stamp provider, as it may contain accompanying folder-level JavaScript (.js) files necessary for dynamic editing features.
Install the Accompanying Folder-Level JavaScript
Dynamic exhibit stamps require a specific background script to function properly and allow editing after placement.
Many downloadable legal exhibit stamps are dynamic and rely on JavaScript to prompt the user for input or to allow name editing. If only the PDF stamp file was installed without the corresponding script, the stamp will behave as a flat, uneditable image.
Open the stamp package you downloaded and locate the attached folder-level script, which typically ends in a .js file extension.
Navigate to the Acrobat XI installation directory and copy the script file directly into the application's 'JavaScripts' folder.
Close and reopen Adobe Acrobat XI to initialize the new folder-level script and unlock the stamp's editing capabilities.

Download the Latest Version of the Stamp
If the stamp is corrupted or incompatible, downloading the latest version from the original publisher can resolve formatting and locking issues.
Upgrade to a Modern PDF Editor
Acrobat XI has reached its end of life and no longer receives updates, which can lead to compatibility issues with modern dynamic stamps.

Frequently Asked Questions
Why can't I edit my PDF stamp after applying it?
Dynamic stamps require a specific folder-level JavaScript file to allow editing. If this script is missing from your software's JavaScript folder, the stamp will behave as a flat, static image and cannot be modified.
Where is the Stamps folder located for custom PDF stamps?
The Stamps folder is typically found in your system's AppData directory under Roaming > Adobe > Acrobat > [Version] > Stamps. Placing custom PDF files in this directory allows the application to read them as stamp tools.
Is Adobe Acrobat XI still supported?
No, Adobe Acrobat XI reached its end of life several years ago and no longer receives security patches or feature updates. Upgrading to a newer, actively maintained PDF editor is highly recommended.
