• Open the Control Panel Windows (you can access it from the start button) and enter Internet Options.
• In the new window "Internet Properties"Go to the" tabAdvanced Options”.
• In the configuration box uncheck «Use SSL 2.0«, «Use SSL 3.0«, «Use TLS 1.0«, «Use TLS 1.1«, «Use TLS 1.2" and "Warn about certificate mismatch«.
