Hello,
I'm using Win 10 Professional on my home computer, and I was trying to connect to a server (client to server scenario).
I temporarily uninstalled ESET and after I was able to complete the Web site certificate installation in the Trusted root Certification Authorities. It appears that ESET was blocking the window to approve the certificate installation.
Finally, I re-installed ESET and I still have access to the web site.
Thank you for the tips,
Joe
