If you are using an older or expired security software, we recommend that you update it with the most recent version from its manufacturer. Even if a security program expires, its firewall component may still be active and could still cause GoToMyPC connection failures. If your security or firewall program has expired, we recommend either renewing the license so that you may configure its firewall or uninstall it and utilize a different security or firewall solution.

GoToMyPC periodically releases updates for both host and client software. You may need to update your security software to the appropriate version provided by your manufacturer in order for it to recognize newer versions of the GoToMyPC software.
