CS6 on Mac EL Capitan - Acrobat Pro doesn´t recognize serial number

Hy everyone,

I bought a new Mac Retina, running on El Capitan and tried to instal my CS6.

Though the instalation supposingly couldn´t be completed, the programs seem to work.

Only I can´t open my Acrobat Pro, when putting my serialnumber, is says it is not correct.

Apple regards CS6 as so outdated (I bought it 4 years ago!) that they didn´t make sure it is running on the new El Capitan.

And Adobe regards it as so outdated, that they don´t offer support.

But today I was lucky to get support from the chat, when I had the same problem with Photoshop. (the serialnumber wasn´t recognized)

I was told to open the host file in my etc folder > save it on the desktop > delete all adobe content > save it > overwrite the old hosts file in the etc folder with the new file and it should work. It did for Photoshop.

Does someone know how to solve the problem for Acrobat Reader too?

Thank you!
