To understand why this happens, we need a little background on cryptography.

At its core, this issue is a security feature functioning as intended. The Windows operating system attempts to validate the digital signature of the .NET executable against a list of trusted root certificates stored in the local certificate store. If the operating system cannot trace the signature back to a trusted root authority—specifically, the root certificates used by Microsoft to sign modern updates—the installation is blocked to protect the system from potentially tampered software.

The installer fails because it cannot verify the digital signature against a trusted root.

When attempting to install on Windows 7 SP1 , many users encounter a blocking error: "A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider" . This technical friction primarily stems from Windows 7's aging security infrastructure, which lacks the modern root certificates required to verify the digital signatures of newer Microsoft software. The Root Cause: Infrastructure Mismatch

Solving the .NET Framework 4.7.2 Certificate Chain Error on Windows 7

Q: How do I resolve the .NET Framework 4.7.2 certificate chain error? A: You can resolve the error by updating root certificates, installing intermediate certificates, verifying system date and time, cleaning the certificate store, using the .NET Framework 4.7.2 offline installer, or enabling the Windows Update service. The Windows operating system attempts to validate the

By installing (SHA-2 support), KB4490628 (SSU prerequisite), KB4516655 (SSU update), KB931125 (root certificates), KB4507456 (SHA-1 deprecation), and finally the latest Monthly Quality Rollup , you can make the system recognize the .NET 4.7.2 installer's signature, bypass the certificate chain error, and complete your installation.

Windows keeps a list of trusted "Root Certificate Authorities." KB931125 updates this list to the latest version.

Thus, when you run the installer, Windows checks the signature, tries to build the certificate chain, fails to find a trusted root, and throws the error:
