"Add to trusted certificates" button is grayed out. Why?

Hi sarahr9691477

You might try the following steps for Acrobat DC/XI:

1- Launch Acrobat>navigate to Edit menu> select Preferences

2- Under Preferences>select Signatures in the left hand pane.

3- Select Trusted Certificates in the left hand pane, select the certificate for which you want to change settings>select Edit Trust

4- Select the following check boxes under Edit Certificate Trust and click OK.

     - Use this certificate as a trusted root

     (ii)- Signed documents or data (if its not already)

     (iii)- Certified documents

     (iv)- Embedded high privilege JavaScript

      (v)- Privileged system operations (networking, printing, file access, etc.)

Let me know if it worked.

Thank You,

Shivam
