AE CS6 won't run after the Mavericks 10.9.3 update

My AE CS6 won't run after the Mavericks 10.9.3 update the other day. I was prompted that the current version of my AE was 11.0, so I searched and found the seemingly most up-to-date here: Adobe - After Effects : For Macintosh : Adobe After Effects CS6 11.0.4 Update : Thank You

My question is this: since I'm new to Mac, should I download the update and install it to my existing instance of AE and it will allow AE CS6 to run as normal? And the way to install the update is simply to double-click the .dmg?

Thanks!
