Acrobat crashes when trying to add my signature

[Amanda386797201qhm]

When I click the Pen icon to add my signature to a document Acrobat crashes. We have tried uninstaling and reinstaling and using the most current version of Acrobat as well as the last version. Any other suggestions?

The same happening to me, and now I can not add pages because it completely freezes. I do really need this tool but is not working at all.

@Amanda386797201qhm @Janeisy3871966607s9  here's a different thought... may I suggest you sign your signature on a piece of paper (white preferably) with your choice of colour pen. Scan it in as a PNG or JPG, and then place that signature as an image. It would be your real signature versus an Adobe Signature. I do this when I need to sign a PDF with my real signature versus using Addobe Signature

The issue with that is I also would have to add a text box to be able to add my notes as well. Two mannual steps to fix a major issue are not viable work arounds long term.

This workaround was VERY helpful...thank you.  I was going nuts trying to figure out what happened since the last time I used Acrobat, when I had no issues at all with respect to affixing my signature.  Do you think the issue arose as the result of a routine MS update or something like that?

[Erica Urzua]

Hi, I have the same issue. I tried to delete the files as you advice earlier but I can't find them nor the location mentioned. I have tried un/reinstaling without success.

Hi ~

This is what worked for me:

1. Access the operating system for the computer, for example "OS (C:)"
(this is the title of my operating system)
2. Open "Users" folder
3. Then find the folder that is titled whatever your name is on your
computer, and open that folder
4. Open "AppData" folder
5. Open "Roaming" folder
6. Open "Adobe" folder
7. Open "Acrobat" folder
8. Open "2020" folder (this is the version of Acrobat that I have; you may
have a different version, such as "DC" -- if you do, open that folder)
9. Open "Security" folder
10. Delete the following files, which for some reason have become
corrupted in your system:

- acrobat_fss_signature_initials
- acrobat_fss_signature_initialsi
- acrobat_fss_signature_initialsk

Open Adobe Acrobat and see if you now are able to utilize the signature
tools.

Let me know if this works for you, if not I'll see if I can find other info
to help.

Cindy

Hi, thank you for your answer. 

I found the files but it did not work. Adobe is still crashing.

It is now September 2025 and this issue began yesterday for me.  I have checked for updates and it says there are none.  I've updated Microsoft.  Has there ever been a resolution for this?  Apparently there is no way to actually speak with a live tech support person? If so, I cannot find it.  Thanks.
