I have a recent problem which I couldn't start my After effects, got After effects warning: Unknown exception.
I googled it and saw my say just delete the AE caches and preference in users/adobe/library/preferences , But I don't have that folder there are no library and preference. Some show to delete it inside when running AE, but I couldn't even start it. I reinstalled like 10 times whether delete it manually right at the folder, via control panel,uninstall/remove program, run C Cleaner, WinDirStat while I can open and run Photoshop, illus, Flash, and others regularly.
Thanks for your answer, but sorry I forgot to mention that I am using windows 8.1.
Furthermore, I tried both cc 2015 and previous 2014, and it show the same error message !!
I used to be able to use it in this computer, but after I had changed OS to another drive (HDD to SSD)
I got this problem
