Assuming this is the 2009 Consumer version we are discussing.
Normally you'd get a pop-up alert asking you if you want to allow a program access or not. If you haven't and it's already installed you can add it to firewall permissions.
Double-click the taskbar icon to open SecurityCenter
Click Advanced Menu (bottom)
Click Configure (left)
Click Internet & Network (top left)
Click Advanced (right)
Click Program Permissions (left)
Add or adjust permissions in the right-hand panel.
I don't see a Security Center - all that comes up is the Virus Scan Console. I can also bring up On-Access Scan and On-Demand Scan. In the Virus Scan Console, my options are:
Buffer Overflow Protection;
On-Delivery Email Scanner;
Unwanted Programs Policy;
Quarantine Manager Policy;
New Scan 100125;
I check my build date - don't remember the exact date, but the year was 2009.
Here's the screenshot, and I also attached the JPG file because I assume the resolution in the posted pic isn't good enough to be useful. I know that Windows Firewall is active, but I have no idea about McAfee's firewall (what it's called, how to find out about it, and how to create exceptions in it).

Moved to VSE.
I am told the following. Doesn't make much sense to me but maybe it does to you.
Other than that there is support available as per your support portal.
that product is Virusscan Enterprise(VSE),
it doesnt have a Firewall but it has 'Access Protection' which can block stuff like a firewall can to an extent...
so if its VSE, then its gotta be the Access protection(AP).
they can right click on AP, and do view log, go to the bottom and see if its AP blocking their application, if not then its not VSE
if so, then the details will tell him what rule, category is doing it to what file, and he can use that info to make an exception...
