They don't send data, they merely open local sockets, which is a whole different thing from actually opening a network connection. It's a fundamental way of how your operating system components communicate with each otehr and applications. You are confusing things here. The only Adobe tools that do occasionally send data or check for data are as follows:
- Adobe Application Manager/ AAM Notifier - updates and patches
- Adobe licensing system - license validation
- Adobe CS Services - online services
- Crash reporter
- Product improvement program
Except for the licensing system, all of those can be disabled in the respective menus and preferences or they are off by default, so never any data is sent.
To add a little to what Mylenium said:
Some of the components of After Effects CS5 and other CS5 programs use TCP (one of the protocols that is also used for internet communication) to communicate with each other within your computer.
These include the Dynamic Link server and the QuickTime server.
We limit the connections to the local machine only (which is enough for most firewalls), but some aggressive firewalls block communication between these components.
If you are having problems with After Effects, then explicitly telling your firewall to allow them to communicate may help.
Here are the executables that might be affected:
Adobe QT32 Server.exe
thanks to Todd_Kopriva and Mylenium for their (detailed) answers.
It seems, that i have to calm down a little bit.
I didnt know, that AE uses TCP to communicate with other programs.....
If i allow the TCP connections, i dont have any problems and CS5 works fine.
