PhysX Fixer

This very simple tool installs the required physx files for Mass Effect 3 directly into the game directory, bypassing the need for the PhysX installer that normally is run when the game is installed. Due to questionable design of the installer by NVidia, the installer will refuse to run if certain newer versions are installed, but they don't have the files or necessary information for ME3 to find the PhysX files it's looking for. This tool bypasses this issue by just placing those PhysX files right next to the game exe, which is where the game will first look to load the dlls. I extracted these physx files out of the msi directly.

To use this program, you just run it and point it at your installation of ME3 that isn't working by selecting the game executable (under ME3/binaries/win32). If your game is in a write protected directory, this program must be run as administrator (it may crash otherwise). That's all there is to it.

Technical info:

ME3 uses 32-bit PhysX 2. 8. 3.

Once the files are installed, your game will have the additional set of files:

These files are from the PhysX redistributable included with the game.
