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 to install the PhysX from here.

You need only install PhysX for dao.Here is the link:
