Re: [CURRENT ISSUE] Several Issues after incomplete Installation
@LQG99 Open Origin, click on "My game library," then right-click on the Sims 4 icon. You'll see a list of options, one of which is Repair. Choose that, and let Origin repair the base game and all your packs.
If this doesn't help, clear Origin's cache, restart your computer, and repair again.

Also, "cc" refers to custom content. If you've never downloaded any, you don't need to worry about it.
