Tell us as much as you can about your system. What is your screen resolution? What GPU are you using? Has After Effects ever worked before on this computer? Why are you using such an old version of After Effects?
"Oh... sorry. I played windows 7 32bit.."
I do not think that is correct. AE CC 2014 is a 64-bit application. It can not run on 32-bit operating systems.
Did you ever solve this problem? Do you have a 64 bit OS? If not, you can't install After Effects. Let us know!
