Problem installing After Effects CS6 on Mac 10.10.5 [Edited]

Hello,

I am trying to install Adobe After Effects CS6 (and to use it as a trial version first) on my MacBook Pro (Retina, 13-inch, Mid 2014, Yosemite 10.10.5), and I think I (partially) succeeded, except that in the end I cannot run it.

And I seem to be able to run both Media Encoder and Bridge, but not After Effects. When I click on it it says the following two things:

What is going on? I have tried to download the last update of After Effects for Mac (AfterEffects_CC_13_2_ftr.dmg) and to install it, but it says that I don't have access to this update. I don't really know what to do next...

Any idea?

Thank you!

Allan
