Sims 4 Steam won't lauch issue
So I've had Sims 4 for quite some time now on my Windows 10 computer. It's on steam ((I also have origin but I bought the game on steam, downloaded it from there, and so on)
I have mods as well. Recently I tried moving my game out of my C to my D drive because my mods folder was too big and messed it up. I couldn't figure out how to reset it to its default file location so I decided to uninstall it and re-install it though I'm having the same issues.
It was previous installed on my C drive in the default area with documents, I reinstalled it though to my D drive where it's currently in my steam's current apps folder. In this area, it doesn't have the mods folder. I noticed sims 4 is also downloaded in my programs file on my d drive Program Files (x86) with sims that have a mods folder.
My Error messages that i get while trying to open it from Steam/origon directly:

My apologies if anything is unclear, I'm very new to this generally.
@ThatsSketchii There are supposed to be two separate Sims 4 folders. One contains the game's program files, as in, the data that Origin or Steam installs. For a Steam install, that data should be here:
...Steam\steamapps\common\The Sims 4
wherever Steam itself is installed. The second folder is the user folder, as in, saves, saved households and builds, mods and custom content—anything you as a user create or add to your game. This folder is located in Documents\Electronic Arts, and if the game doesn't find a Sims 4 folder there, it creates a new one. It won't read a user folder anywhere else, so if you add mods to some folder within Program Files (x86), those mods won't be loaded.
For the error in your screenshot, please clear Origin's cache and uninstall it "the hard way":

Download the full Origin installer and run it as an admin: right-click on the download and select "Run as administrator." This is a direct download link:
http://download.dm.origin.com/origin/live/OriginSetup.exe
Run both Steam and Origin as an admin as well, then try to open Sims 4.
