--- Comment #4 from Juan Lang juan_lang@yahoo.com 2011-01-30 20:51:07 CST --- Looking at the logs, I don't see how the identified commit can cause the failure. The only modified function is verify_base_policy, which is called by CertVerifyCertificateChainPolicy. The only times this is called in the log, it returns TRUE, i.e. success.
Does reverting the commit help? If so, please attach a +wintrust,+crypt,+chain log of a succeeding installer.
