EA app telling me The Sims 4 is uninstalled when it isn't

Avacrest  No, the Delta folder is where Sims 4 is installed, so you were supposed to delete the entire Sims 4 folder Delta was in.  The point was to find that folder since you didn't already know where it was.  If you can't find it again, run the pack search I listed, which should take you to the same location.

puzzlezaddict  I deleted Delta, it doesn't change anything. I thought deleting it was supposed to clear out all the space the sims 4 was taking...

Avacrest  Search your computer for a Delta folder and jump there.  (Open a File Explorer window, click This PC in the left panel, and enter the word in search field in the upper-right corner.)  It should be inside the Sims 4's program files, and you can simply delete this folder and reinstall the game.

If you can't find Delta, look for the folder name of any pack you've ever installed.  Here's a list:

Keep in mind that these searches can take a little while, so blank results for a couple minutes doesn't necessarily mean no results.

Hiii please I still need help???

puzzlezaddict I unfortunately don't have space on my pc to do that. I only have 20GB left and the game requires 23GB space. The game is somewhere in my computer taking space already :(

Avacrest  Try "downloading" the game to its current location.  But make sure you're not installing it anywhere within Documents.  If that's where it was installed before, pick a different location.
