The certificates appear as valid now. The problem was that our Proxy server required Authentication. If I change my proxy server that does not require authentication the certificates appear as valid. Has anyone else faced a similar issue? Is there a way to get around this? My installers are signed with "Developer ID Installer: MyCompanyName". As per my understanding digitally signed flat installers require net access the first time the application is installed to authenticate the certificate. Please correct me if I am wrong here.
