sims 4 won't launch

@chanicedaviana  Do you mean you moved the Sims 4 folder to your desktop?  If so, the content isn't gone, it's still intact in the folder you moved, but the game can't read the files where they are now.  That's actually the point of this test: to see whether Sims 4 works with no added content.  If it does, you can start moving your mods and other content to the new folder in Documents > Electronic Arts, testing as you go and removing anything that prevents the game from loading properly.
