Unable to sign after imported logo as custom watermark in signature

[scpham]

Hi all,

I am using Adobe Acrobat XI Standard (11.0.23). Recently I tried to add my company logo (changing the watermark) to my digital signature following the guideline in this link https://www.adobe.com/devnet-docs/acrobatetk/tools/DigSigDC/appearances.html. 

However, I am unable to sign pdf document after I saved SignatureLogo.pdf in C:\Documents and Settings\(user name)\Application Data\Adobe\Acrobat\(version)\Security.

Below is the error I received. 

I am missing something here or there are hidden steps that I am not aware of?

Thank you for your supports.

Hi scpham

Hi Amal,

Thank you for your support. I tried the link you sent and found that:

- Re-create the digital ID didn't help. Still received same error.

- Unable to rename Crypto folder, the following error code received.

Appreciate if you could provide other solutions.

What happens when you remove SignatureLogo.pdf?

When I removed the SignatureLogo.pdf, all worked as usual with the Adobe logo as watermark.

Then is something wrong with this PDF file. Have you created it with Illustrator?

Hi Bernd

I do not have Illustrator on my computer so I converted company logo from PNG to PDF. Not sure what is the difference between a PDF file created by Illustrator vs. other normal PDF file. 

As I understood from the instruction "Import a logo or create a new one in a program such as Adobe Illustrator."

Hi Bernd

All's working good now. Problem is the PDF file. I created another file using Illustrator and problem solved. Thanks a bunch.
