Same problem as above posts.
I tried uninstalling and re-installing AfterEffects CS6, but still the same problem; CS6 wont open, and when I try to run the 11.0.3 AdobePatchInstaller, it gives me the following message (which is eroneous, since I am logged in as the Administrator, and their only solution was to de- and re-install AE anyway).
I also tried updating the Application Manager and it simply tells me that all my CS6 software is up to date, suggesting that it isn't factoring in the 11.0.3 update.
If it says that updates have been suppressed by the administrator, then it means that your software was distributed as part of an enterprise license agreement or similar, and the person who deployed the software disabled updates. This is sometimes the case for software deployed at educational institutions. This is something that you need to take up with your IT people who deployed your Adobe software.
