3. Disable Real Time Protection or Exclude Folders on Anti Virus: all folders used to download the game and also the folder where the game is going to be installed into;
4. Download It [Link Below];
The steps to install this version of The Sims 4 All in One Customizable with the NEW October Patch Version 184.108.40.2060 (EA is a bit insane with those version numbers) are in the video above. Even though it was made originally for a previous version of the game, the procedure is the same.
Basically, you need to disable your anti virus (or exclude the download and installation folders from its real time protection), download the release, run the setup file, choose the language, the installation options (if you want a full or partial install etc) and confirm everything. Then, before playing, always make sure Origin is not running in the background and have fun!
