The Sims 4 won't work after I installed the Games4theworld City Living

So I installed the games4theworld  city living and followed all the instructions but now my game won't work. It asks me to open origin. I've seen other people have been same problem and i'd like to continue playing my game (haven't been able to play for a couple days)

PLEASE HELP!!

Basically there are 2 reasons for this error to pop up.

1. The crack in Installationfolder\The Sims4\Game\Bin has been destroyed by your anti-virus program.

2. Origin is somewhere active on your computer
    Open Taskmanager (Ctrl+Alt+Del) - Processes and check for instances of Origin and close these.
