Error code 16

Ok,first be sure you respected this permissions for those folders :

PCD:

Owner = System = read/write

Group = Admin = read only

Everyone = read only

Or from the terminal, drwxr-xr-x root admin

SLSTORE :

Owner = System = read/write

Group = Admin = read/write

Everyone = read/write

Or from the terminal, drwxrwxrwx root admin

otherwise,try this because sometimes changing from permissions menu doesn't take effect :

open the terminal (Applications > Utilities > Terminal)

Tape this :

sudo chmod 777 /Library/Application Support/Adobe/Adobe PCD/

sudo chmod 777 /Library/Application Support/Adobe/SLStore

This is a permissions problem,if you're on windows,try to right click on the application and choose run as administrator
