Re: Won’t let me save household and start game

@artyure26  It sounds like you moved the game's program files, not the user folder.  With the program files moved, the EA App would think Sims 4 wasn't installed and would prompt you to download it again.  Moving the user folder has no such effect; it would simply remove (but not delete) any saves, mods, etc. you'd created or installed.

Before doing anything else, please check the location where the App has installed Sims 4.  Open your game library, click Sims 4, select Manage > View properties, and you'll see the location there:

This can be almost anywhere, but it cannot be in Documents for a few reasons, including the one you may have just encountered.  If Sims 4 is in fact installed into Documents, please uninstall it and install somewhere else.

Please also have a look at the contents of the Sims 4 folder you moved.  If it has subfolders like Data, Delta, and Game, it's a (now not functional) copy of the program files, and you should simply delete it if you've reinstalled Sims 4.  This is especially important because your dxdiag shows your C drive has very little free storage, so you need back all the space this copy of the game would be occupying.  Empty the recycle bin after deleting the folder and then restart your computer.

Once you've done that, and made sure Sims 4 is installed elsewhere, try again to play.  If you still can't save the household, let me know, and we'll go from there.
