Hi luvjetz, a common reason for that error is a "man in the middle" of your connection. Let's see whether we can sort that out.

Thanks jscher2000! I copied the certificate to certlogik and found a middleman proxy. Deleted the middleman and am able to access Google. Now on to working with the middle man so that I can still have it installed...
