I have a question regarding firewalls. We are developing a legitimate program at the company i am working for. We are sending out cds and the users install it on their computers. Then, they have to register it online and update their account information and/or download new updates once a month.
The problem is, if they have a firewall software or an anti-virus software (mostly norton or mcafee) the data that our server sends is being blocked. so they can neither register nor download the updates, which creates a big hassle for both us and them, since they call us and we have to tell them to disable those software temporarily. but most of them don't even know what a firewall is.
Anyway, is there any way to fix this problem? something that we can do during the installation process for instance? Or simply, if there is a firewall, there is no way our server can send the data to their computers? Thank you very much in advance.
