Trusted Root Certificate Not Validating Signatures

Question

I'm having issues validating all digital signatures created from a certificate authority.

I have the root certificate in the Windows Certificate Store under "Trusted Root Certification Authorities". Trust ALL root certificates in the Windows Certificate Store for validating signatures is selected in preferences. Yet when I sign a document with a digital signature created under this CA, it still fails to validate. It will only validate when the actual digital signature cert is added. I'm looking to have all digital signatures created accross our company's CA be validated by only the root cert.

Any ideas why the root certificate is not providing validation here?

(Using Acrobat Reader DC and Acrobat Standard DC)

Thanks

Can you briefly describe the steps that you've followed with Reader DC to try to validate the signatures?

Or is it simply not letting you adjust any preferences settings in Security, Security Enhanced and Trust Manager sections?

Figured it out!

For some reason I have to disable "Require certificate revocation checking to succeed whenever possible during signature verification" within Acrobat Reader. But didn't have to do this within Adobe Standard.

Any ways, it's all working now. Thanks for your input!

Did this problem started happening recently after an recent upgrade or update in your system? Are all root certificates the most current ones from the CA authority?
