This error can occur if both these conditions are true:
Digital certificates contain data about the organization from which they were issued. This data forms a “certificate chain” that ends in a trusted root certificate of a known CA. If the trusted root certificate is not installed in the operating system, Windows uses an automatic update mechanism to download the necessary root certificate from Microsoft.
Some versions of Windows (for example, Windows 8) do not include all the trusted root certificates necessary to validate time-stamped digital signatures. If these systems also do not have Internet access, the automatic update mechanism will fail.
