A year or so ago, i collabed with a co worker and made a digital stamp from our physical ink stamp. We added drop down lists, text boxes, etc. We then saved that df stamp in c:>program files>adobe>acrobat dc>acrobat>plug_ins>annotations>stamps>ENU. With that file open in adobe, i could change the info in the drop down lists, and then when i go to another pdf, i can select add a stamp>stamp, and it shows up there to select and put on the current pdf file. Basically what im doing here is stamping an invoice for approval. We recently changed some info so i created a new stamp. I added drop down lists and text boxes, i put the same custom calculation scripts in the appropriate boxes so the stamp populates just like my old one did. The problem im having is when i then save thos new stamp in that same ENU file path folder, it is not showing up under the stamp function like the old one does. Im certain im missing something somewhere but cant for the life of me figure it out. Please help if you can

All stamps of a same group are located into a same stamp file.

So, to add a new one, jus must Manage Custom Stamps, then choose “Create...” and indicate the location of the stamp file, the category and the name of the stamp.

The stam will be imported as an image, So you will have to open the stamp file and paste all fields you already created.

FYI, the name of the group is the title of the pdf file.

The name of the stamp is indicated in the name of the page template of each stamp, just after the “=” symbol.

Did you remove the old stamp file? Did you give the new stamp a new “stamp name”?

Here’s an old article I wrote on Dynamic stamps, but it also covers how stamps work:

Just to be safe, can ou confirm the exact version of the software and operating system you are using?

Also, can you confirm that you see the ‘old’ stamp in the folder you are adding the new one, and you have administrator access to your computer?

Acrobat pro. 2026.001.21529. Operating system is windows 11, 25H2. I do have admin access to that ENU folder, not to the entire machine though.

Hi @Mikejd3,

Thanks for reaching out and for the information:

Based on the information provided, the stamp PDF itself appears to be functioning correctly, since the dropdown fields, text boxes, and scripts are behaving as expected when the file is opened directly in Acrobat. The issue may instead be related to how Acrobat is registering or refreshing the custom stamp list.

You may try the following suggestions:

Ensure the new stamp is saved as a PDF and fully closed before copying it into the stamp directory
Close Acrobat completely and reopen it after placing the file in the ENU folder
Rename the new stamp PDF to a unique filename, as Acrobat may still be referencing cached stamp metadata from the previous version
Try importing the stamp through Acrobat directly using:
Comment → Stamps → Custom Stamps → Create

Additionally, newer Acrobat versions may use the user-profile stamp location instead of the Program Files directory. You may therefore also want to test placing the stamp PDF under: C:\Users\<username>\AppData\Roaming\Adobe\Acrobat\DC\Stamps

rather than: C:\Program Files\Adobe\Acrobat DC\Acrobat\plug_ins\Annotations\Stamps\ENU

Based on the details shared, this appears more likely to be related to stamp registration/cache behavior rather than the JavaScript or form logic inside the stamp itself.

For more information about dynamic stamps, please read the following. https://helpx.adobe.com/acrobat/desktop/share-and-review-documents/use-stamps/automate-date-time.html

Let us know how it works.
