You can download it from nvidia here: http://www.nvidia.com/content/DriverDownload-March2009/confirmation.php?url=/Windows/9.14.0702/PhysX-9.14.0702-SystemSoftware.msi&lang=us&type=Other

If that link eventually expires, google nvidia PhysX download, it'll likely be the top result.

Although this problem is fixable, it's still inexcusable that as customers we have to work out the problems ourselves, although I understand it's impossible to know every single bug, when discovered EA should have fixed this problem.

Edit:

It seams that although installing the above fixes it, it only works when launching through origin. If you launch it through steam as a non-steam game, it gets the same error (at least it does for me). It's not a major issue, but being able to have games all in one place would be nice.

I am having the same issue. I have a directx folder. Tried using the same process and it didn't work.

try direct-x

same

Some versions of the game force other similar programs, dependent of type of computer used or other compatability issues. All the same, you should be able to fix the issue by following the pathing the original poster presented, just switch out PhysX with *x file folder... For example, my computer uses DirectX... My pathing is programfiles(x86)/origingames/dragonage/_installer/directx  So if you can't find PhysX, try looking for DirectX, Box2Dx, FleX, or APEX app file and install that way.
