Hi,
I have the problem with update AATL and EUTL lists.
I've been looking for where the problem is for a long time.
I did some tests and it turned out that the file name [USERNAME] C: / User / [USERNAME] if it contains a letter from the Polish dictionary, e.g. Ł, Ż, etc.
This makes it impossible to update the AATL and EUTL lists.
As a result, the electronic signature on the file cannot be verified.
Adobe help please how to solve the problem. The names of user folders are created automatically when a user logs in from Microsoft Azure Active Directory.
Best,
I can confirm that this is the issue.
Both my wife and me have special characters in our names and both our machines had issues with "UNKNOWN" being shown for certificate validity, because Adobe Reader was unable to update the EUTL list.
I have renamed the user folder by following this tutorial: https://www.elevenforum.com/t/change-name-of-user-profile-folder-in-windows-11.2133/
And afterwards, in Adobe Reader I've updated the AATL and EUTL list (Menu/Preferences/Trust manager).
Now it works as i

Now it works as it should, showing "Signed and all signatures are valid".
Thanks Piotr for this post, you've saved me a ton of time.
**Adobe, it's been 3 years and you still haven't solved this issue?!?**
