This worked for me! Run the updater in the same folder the EA App .exe is located in.
For anyone else that needs more guidance:
- right click the EA icon on your desktop and click 'open file location' (you might have to click the show more options at the bottom to get the older menu up, that has this in it)
- In the folder that opens you need to look for 'EAUpdater'.
- Run this as administrator - again right click the file and you find this option there.
- A command prompt black window will open and download some data, this will then say something like 'staging install' or something. When the command prompt window finishes you should be working again!
