Thanks for your reply. I managed to solve it by reinstalling the After Effects CC. This error occurred when I haven't updated my laptop , especially the video card updates. Therefore , optix.1.dll is only 0kb as a file , in the support file for AE cc.
I hate the GeForce experience by Nvidia. One of its updates caused Windows to prevent starting. I have to reinstall Windows and reinstall Adobe Creative Cloud, hence the issue. Thanks Todd , will always be an Adobe supporter.
