Orgin Not Running Error

I have scoured the forum for a fix for this but nothing I have tried works. My game was running fine until about 3 days ago. I didnt install anything new or change anything with the sims 4, I had a fully updated and working version of the game. However randomly 3 days ago I try to launch the game and it tells me Orgin is not running. I don't even have Orgin on my computer never have, and this is the first time I have gotten an orgin error. I uninstalled the game completely then reinstalled, I have the proper folders in the antivirus exceptions list, I used the error code 3 fix, I used the update only fix, I made a new game folder and renamed the older game_. I am at a total loss now as to what could have possibly happened. I can post screen shots of whatever I need too just let me know if there are some ideas to what could be happening here.

Hi. Actually I already did reinstall after trying that link you put there for the ultimate fix. I do have every sims 4 game, expansion, update, and stuff pack that you guys have available on your download site installed, also my folder is not in the EA folder. I have been using this site for a long time so I know I have installed everything right and have it in the right places. I tried each fix i found one at a time and tried running it after each time and nothing worked. I don't even get any other errors just this origin one. I am uninstalling and trying again one more time with everything while following the step by step guide. I will post my results again soon.

Okay I have completely reinstalled everything in the correct order. Now rather than getting a error message about origin the thing wont open at all. It opens for a fraction of a second then closes out. No warning or message. At this point I have my virus protection completely off.

Heres what my sims 4 folder looks like currently.

As I am installing/removing/re-installing pretty often it always struck me that a new installation and/or a new Sims-folder caused the game to start very slowly.
You click on TS4 or TS4_x64 (or a shortcut), the cursor blinks for a short while and then ..... NOTHING !
But have a close look at the LED showing the activity of your HDD and you'll notice that it blinks or even constantly burns.
So, just have patience.

I do have a pretty good PC, but yesterday after testing a new way of downloading/installing the Sims 4, I started the game, went down for lunch and after about 30 minutes a heard the tune of the Sims 4.
