A certificate chain could not be built to a trusted root authority

Question

During the installation of .NET Framework 4.6.2, I got an error:

.NET Framework installation failed: -2146762486. A certificate chain could not be built

Answer 1

Had the same problem, almost. visual c++ error 0x800b010a could not find the certificates to download. Installed firefox and then retried to install c++ and problem fixed. Must be firefox browser installs these certificates.
