The Sims 4 Unable to Launch

Hello,
 
So I recently decided to install The Sims 4 on our PC, as I was enjoying it on my laptop, and found a few problems.
 
Before I installed the game, I first uninstalled Origin because apparently it was installed on our PC. Afterwards, I installed the base game and then installed Get To Work, but the game wouldn't launch. I wasn't so sure if it was because our PC is old (although it meets the minimum requirements needed for the game to run), or if I did something wrong in the middle of the installation. So I uninstalled the game and reinstalled it.
 
When I tried launching it again (without Get To Work installed), this error would come up:
 
Unable to start:
 
The contents of your user data directory were created by a newer version of The Sims 4 and cannot be loaded. Please update via Origin to play.

I tried looking around the forum for any possible solutions, and I was able to fix it. However, the game still wouldn't launch.
 
I was thinking it had something to do with the possible remnants of Origin still being in our PC, so I quickly searched how to get rid of Origin completely and followed the steps. I uninstalled the game again and reinstalled.
 
However, it still wouldn't open. I tried installing Get To Work, hoping that it could fix the problem, but still no luck.
 
When I try to launch the game, the screen becomes black, as if it were switching to the game, but then it would get back to showing the desktop shortly after.
 
I'm not sure if I did anything wrong with regards to the installation, because I made sure that all the steps included in the installation guide were followed. I turned off my anti-virus, added the folders to the exceptions list, and so on.
 
Can anybody help me with this? I badly want TS4 on our PC (because my brother would be using my laptop more frequently from now on for his internship) because it's the only productive thing I do during day.  


//EDIT:
I've also tried restarting our PC several times, but still no luck. (Hopefully this info might help in some way?)

Hi Carlos,

I've never had The Sims 4 installed in the PC before. Anyways, I did as you said, and it finally launched! I actually did the exact same thing to try to get the game to work, but I'm not sure why it only decided to work now. Thanks so much, Carlos!
