There's a mandatory AIM 6.8. update. I did it with AutoIt. You can run this without logging in. After you're done and login to AIM, it asks you to install a second security update! Sandboxie is also a good way to quickly see file/registry changes.
run("C:\Documents and Settings\Administrator\Install_AIM.exe")
winwait("AIM 6 Installation", "I Agree")
controlclick("AIM 6 Installation", "I Agree", "I Agree")
