I've been troubleshooting an issue in our organisation where users can't sign documents using their Root CA issued certificate. By "can't sign", I mean the sign button in the "Sign Document" dialog does nothing. This only occurs in Acrobat Pro X. Adobe Reader DC is fine.
The problem applies to any SHA-256 certificate stored in the Windows Certificate Store. The same certificate exported from the certificate store and imported into Acrobat Pro directly, works. Has anyone seen this issue and know how to work around it?
Cheers
