Although I know firewalls to a certain extent, I have never had to configure this setting.  We are getting a runtime error for a piece of software and the support people are telling me its because the updater doesn't have access to the internet through the firewall.

You can't control access for a specific application, but you can allow outbound access from the IP address of the host.

I mean they have standard internet access on this machine.  Do you think the firewall would be stopping this one file from accessing the net?

It would not be.      The ASA would not be doing this for a specific application.    There is QOS where you can prioritize traffic based on known protocols or specific ports....  but if you don't have that setup, it wouldn't come into play.  

As a test, hop on that machine and see if you can get outbound.    Make sure the local windows firewall or iptables isn't blocking outbound traffic (you can shut it down just for a quick test).    

On the ASA, you can always have the host make an attempt then issue a SHOW LOGGING on the ASA.  Any dropped packets will be listed along with a reason for the drop.
