I have installed Windows 7 64-bit and I get an untrusted certificate error when visiting any website served via SSL, like Google.com, Gmail.com, etc.
I tried this using Firefox, IE and Chrome and it happens in all three! I installed all updates, but that didn't fix the problem.
I reinstalled Windows again and without installing any program or driver, tried to visit SSL sites, but the problem still exists!
Note that when I install Windows 7 32-bit, I don't get any error and everything works! and my windows date/time is correct.
Did anyone have a problem like that?
