The "certificate chain" is a hierarchy of trust. For Windows 7 to trust the .NET 4.7.2 installer, it must trace the installer’s signature back to a trusted root certificate authority (CA) like DigiCert or Microsoft itself. In many Windows 7 environments, the specific intermediate or root certificates required to validate the 2018-era signature were not present locally. Furthermore, Windows 7’s automatic root certificate update mechanism often failed to function correctly on unsupported or outdated builds. Consequently, the operating system would look at the digital signature, fail to find a trusted anchor in its local store, and terminate the process with a certificate chain validation error, effectively treating the legitimate Microsoft software as untrusted code.
