Re: EA App asking to redownload Sims4

@Aly1233  The easiest fix is to just let the App download the game again.  If you choose the same location as you've always been using, the App may simply verify the already-present files instead of downloading them and then finish the install process.

As for why this happens, the most common cause is an antivirus blocking or quarantining some element of the game.  If you haven't already, set exceptions for TS4_x64.exe and EADesktop.exe.

Your build should still be intact if you saved it before quitting the game.  Builds are stored in the user folder, not in the game's program files.
