trouble installing an em client up date(7.2.34062.0) and windows 7 pro firewall

EM Client working well no trouble receiving/sending email but each use get message up date available and click on yes to update it but it does nothing and can’t continue with update like trying to install the update goes no where. How to continue to be able to install updates and suspect that windows firewall might be blocking program maybe and I did try to add program into allowed programs through firewall.
