Adobe installers fail with a download timeout at 64%.

This has been an issue for a while. Windows XP, 7, and Windows server all fail to update. I did a some packet sniffing with no luck.

There is an option in my firewall to exempt a URL from monitoring. I have never had to do this but a couple of times in the past but it worked.

adobe.com - exempt

Now my firewalls no longer scan Adobe traffic for viruses and such but we can update Acrobat and Flash.
