Re: Can't Access the Legacy Edition

@BansheeHVO  Unfortunately, a number of people can no longer go back to Origin, for reasons that are unclear.  I also don't know whether you can in fact run the Legacy Edition in the App.  But a quick and dirty way to try to force it is to trash TS4_x64.exe, which runs the standard (64-bit) version of Sims 4.  If you originally installed through Origin, it'll be here:

Program Files (x86)\Origin Games\The Sims 4\Game\Bin

I have no idea whether this will actually work.  But if it doesn't, just put the .exe back, or repair the game to restore it.  Open My Collection, hover over the Sims 4 icon, click the three dots, and select Repair.
