Adobe has released a newer version of their software suite called Adobe Creative Cloud but some people out there are still using Adobe Master Collection CS6 for some reasons. However, both of this software suite will face some problem running on the newly released Mavericks. To fix this problem you have to install the updates for those softwares. Follow the link below for more information about this update.

All other software excluding After Effects seems to work well without the update but there's no harm in updating all software included in the software suite though. For much faster process i chose the offline updater by downloading standalone installer here. Be sure to download the right version to avoid any other problem later.

Update progress for After Effects CS6

After finish updating I open up After Effects and go to After Effects > About After Effects and there it is; it's updated to version 11.0.3 successfully.
