We're quoting Branislav Milic:
ADOBE ALERT: DO NOT INSTALL THE TRIAL VERSION OF AFTER EFFECTS CS3
This applies to the Mac platform, I have not tested it on Windows.
When you install the trial version of After Effects CS3, be aware that you will not be able to use the CS3 setup-application for adding/deleting/uninstalling components anymore. You'll have to re-install your entire Mac.
