Unable to use a certificate on a PDF in Acrobat

When clicking on the "use a certificate" menu option under tools, all of the options underneath are greyed out and I cannot select any of them to create a box for a digital signature. I'm fairly certain all of the correct certificates are where they're supposed to be on my laptop, not sure if its something I'm missing in the Adobe app itself? I've had no issues signing PDFs with this certificate in the past or with filling out PDFs. I'm just not able to create a signature block??

    Hi @jan_zil,

     

    Hope you are doing well. Sorry for the trouble with using certificates in Acrobat Reader.

     

    Even if the certificates show up on the certificate manager, there could be high chances that they need to be reimported to Reader for usage. To do so:

      1. Go to Menu > Preferences > Signatures.

      2. Under Identities & Trusted Certificates, click More….

      3. Make sure your certificate appears under Digital IDs.

      4. If not, click Add ID > Use a Digital ID from a file or Windows Certificate Store.

      5. Import it again if necessary.

    More info about working with digital certificates can be found here: https://adobe.ly/42M5Ev3

     

    Hope this helps.


    Regards,
    Souvik.

    The certificate appears under “identities & Trusted Certificates,” but the “Use a Certificate” icon stopped appearing under “All Tools.” How do I restore it to “All Tools”?

    Hi @finley_0472

    I hope you are doing well, and thanks for the update. Having your certificate show up in Identities & Trusted Certificates while the “Use a certificate” tool is missing from All tools is confusing, and we want to understand what is happening.

    Could you please share:

    • Whether you are using Adobe Acrobat or Adobe Acrobat Reader, and the version (Help > About Adobe Acrobat)

    • Your operating system and its version (Windows or Mac)

    • A screenshot of your All Tools screen (please hide any personal details)

    • Is this an issue with a particular PDF file or with all the PDFs? Please try with a different PDF file and check.

    • When you last saw the “Use a certificate” tool, and whether anything changed after that, such as an app update or a new install

    Once we have these details, we can guide you to the right steps.

    Regards,
    Amal

    Ended up finding a solution, you have to select print and then under the printer selections, "Microsoft print to PDF" and save it as a new PDF. Problem solved!

      This solution did not work for me - we still have a totally grey screen when trying to add a digital certificate, this only started after the latest Adobe update with the "AI Assistant"
