Problem running sims 4 [Origin]

Hi guys,

I'm new to this forum so please be gentle.

So my problem is: 

I played your games + ultimate fixed for a long time from both sims 3 and sims 4 so first thank you for that!

I tried to install the ultimate fix (5 parts) for sims 4 today and it didn't work.
At first I found out that my antivirus was blocking a lot, so I wiped everything, turned off anti virus and tried it again.
Now I reinstalled - Base game + fix - and it's still not working. I keep getting the origin not running problem.
I looked through the forums to find an answer but I tried everything.

Things I tried:
Moving the folder from electronic arts.
Reinstalling twice.
Running origin both offline and online.
Running as administrator. 
Replacing only the origin files again.

I haven't had any problems before with your games so please tell me what I'm doing wrong.
I just normally unzipped them (using WinRar) into the destination folder and I do believe every file is there.

Anyway thank you for reading and helping me!

Regards, Kylie.

Did you re download the base game and fix? Your antivirus could have pulled the rld.dll file from the download. Go to where ever you put your The Sims 4 folder, the one from the Electronic Arts folder. Check game > bin. See if rld.dll and RldOrigin.dll are in there.
