The game does not want to open!

I had The Sims 4 version from skidrowgamesreloded, but I want to check The Sims Demo, so I install it via Origin. I played like 5 min but resigned and uninstall when I heard my custom music in the game. I tried to install TS4 from games4theworld but it doesn't open. No information, nothing. (I install it correctly). Next, I tried again install from skidrow but this also doesn't want open. Information says something about Origin. Will I still be able to play Sims? Or I screwed everything when I install Origin and Demo Sims? Please help me.
P.S - Antivirus is off.

IF
the error message is something like different version, update via Origin:
Go to the folder user\Documents\Electronic Arts\The Sims 4.
Delete the file GameVersion and start your game again as an Administrator

OR
The error message is about Oringin not open
Make sure Origin is closed on your computer, check taskbar next to the clock
Do an ALT+CTRL+DEL tab Processes, stop Origin

ELSE
Go to the folder User\Documents\Electronic Arts.
Rename the folder The Sims 4 to The Sims 4_old
Now start your game again as an administrator (Rightclick on the shortcut)

END IF

Still problems, please report

I installed base game and everything was good. Next I copy files from gtw,gt and cl and it won't open. I tried your way but it didn't work. Blank screen and  message:"Unable to start. Origin is currently not running. Please make sure that Origin is running before attempting to play the Sims"

Origin is not installed.  (From Expansion Pack files I just copy files to ProgramFilesx86-EectronicArts-The Sims4.
