how to download battlefield 4 update

[ljkit]

Battlefield won't open until an update is done.  

YOU NEED TO INSTALL OR PATCH THE GAME BEFORE PLAYING.

Where do I find this patch?

@ljkit The game will patch when you launch it. On which platform are you playing?

I don't know much about the technicalities but it is a campaign, single person.  I know it is not a cross platform.  It used to work on my old computer but I haven't played it for a couple of years.  Sorry I'm not much help.
