do this
you need to install the sims 4 trial time if it's allready used so you can't do that
and when it starts to download pause it and after copy your game from your current folder to you origin games folder you will see sims 4 folder put all contents in it if you don't see it then create it
and after continue downloading the time trial version it will get up to 88% I gess and when it complete choose to repair it by clicking in the right mouse and select repair game
when it repairs it close origin and recopy your game to another folder or to your previous folder and crack it with the new ultimate fix with the packs and it should work without problems
am not an admin or moderator but when I did it it worked I hope it will work for you too
