If you see this error whilst installing Sitecore 9.0.2 the issue might be due to multiple certificates been issues.
In this case delete both certificates listed –
Get-ChildItem Cert:\LocalMachine\Root\<<Thumbprint>> | Remove-Item
Try the installation again
Check and remove – DO_NOT_TRUST_SitecoreRootCert if its expired from Local Computer and Current User.
Also remove the same form the dis mainly from C:\certificates
