This error is but a consequence of running an unpatched Windows 7 environment. With Windows 7 end-of-life (January 2020), Microsoft no longer issues new root certificate updates for it unless Extended Security Updates (ESU) are active. For production systems still on Windows 7, ensure rigorous patch management or plan migration to a supported OS.
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. net framework 4.7 2 windows 7 certificate chain error
The .NET Framework is a software framework developed by Microsoft that provides a large library of pre-built functionality, known as the .NET Framework Class Library (FCL), and a virtual execution environment, known as the Common Language Runtime (CLR).
