I'm new to Creative Cloud. After installing, I find out that After Effects cc doesn't run on Mavericks yet. I was directed to the 12.0.1 patch, but when I try to install it, I am told "Updates could not be applied. This patch is not applicable for you." Then it says to contact customer service...which leads me here.
Please help. I need to get this working asap.
Be sure that you are signed in and have activated the software—i.e., ensure that you are not running After Effects in free trial mode. The update will not work if you are running the application in trial mode. Sign in to Creative Cloud using any Adobe Creative Cloud application on your computer to activate all Adobe Creative Cloud applications on that computer.
If you’re not using a trial version, but you’re seeing the message that the update is not applicable, try one of these tips to force the application to be recognized as activated: Sign out of and then back in to Creative Cloud to refresh the activation state. Also, launching the After Effects render engine (not the full After Effects application) can refresh the activation; the render engine doesn’t have the crashing problem that the full unpatched application does.
