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

Just wanted to say that I had a similar issue with trying to install .NET 4.7.2 on a Windows Server 2008 R2 box. I had to first upgrade it to Win 2k8r2 SP1, then add the prerequisite update for the d3ddecomplier.dll (KB4019990), THEN I had to load the certificate store as outlined above. It was only after all that that I was able to finally install .NET 4.7.2.
