I had this exact same problem when I was installing the Trilogy edition. There are two specific releases of PhysX that you will need in order to get all three games to work, and you'll need to install them sequentially to get everything working properly. First, make sure you uninstall whichever version of PhysX you currently have installed. Then, download and install version 09.09.0814:

Once you have that installed, download and install version 09.11.1107:

That got all three games working properly for me.
You might want to keep those two versions of PhysX handy somewhere in case you ever have to reinstall.
