Trying to add exceptions to windows 7 and 8 firewall on instilation

What im trying to do is add a section to my installers that either adds the updater exe to the windows firewall when the game installs or prompts the user to allow the exception on instilation. And then to remove it on uninstall. Any ideas how i might accomplish this. I found a bit on the forums but that was for xp and vista. Thank you all for your help in advance.
