  • This is not an issue actually. You just have to add the publisher certificate to your trusted root authorities certificates repository.
  • Visit https://www.symantec.com/theme/roots
  • Download the Root package for VeriSign Certificates.
  • Unzip the package and open > VeriSign Root Certificates > Generation 5 (G5) PVA > VeriSign Class 3 Public Primary Certification Authority – G5.
  • Double click the certificate and click Install Certificate.
  • When prompted for location make sure you add them in the following repositories.
    • Root Authority
    • Trusted Root Authorities
    • Third Party Root Authorities.
  • This will resolve the issue.
