Hi all,
I came to know the reason why CCS doesn't work. My company use 'Symantec Endpoint Protection' anti virus s/w. And I can't delete it.
If you use that software. please check the version of that s/w.
If you have version 12.x.xxx.xxx, you can solve that by changing it's option.(Change Settings -> Client Management -> Configure Settings-> General -> Application and Device control -> uncheck option)
If you have older version, you must update 'Symantec Endpoint Protection' to the last version. Or please delete 'Symantec Endpoint Protection' and use Avast. ^^
