Hi @BlondySims - The updates themselves shouldn't be throwing that error if you have 3 GBs available. Since it's been a while since you played TS4, is it possible that the game is trying to download expansion packs? If you purchased, but haven't yet installed, Island Living or any of the other expansion packs, those may need additional space to download and then install. But the patches themselves are fairly small.
Make sure you're clearing space on the correct drive; patches and dlc's get installed to the Program Files folders, not My Documents. The default installation path is C:\Program Files (x86)\Origin Games\The Sims 4 Please check to be sure that you are clearing space from the drive that has The Sims 4 program folder on it.
If you are still getting this error, try going offline (in Origin, click the Origin menu > Go Offline) and then launch The Sims 4. Play a little bit to make sure the game is playing correctly (you don't have to save game, just make sure it runs) Reply back with any error messages or problems you may have, and attach a DxDiag.
