Unable to install physx software for Mass Effect 3 .Error Failed to initialize the physics system.

Original title: fatal error installing physx even after using the shortcut and adding /quiet to the target


I tried to install physx to play Mass Effect 3. However a message pop up and the installation was terminated

"Failed to initialize the physics system."
"Please ensure you have an updated version of the PhysX System Software installed."
After reading some online posts I created a shortcut like
C:\Users\USER\Desktop\PhysX-9.12.0613-SystemSoftware.msi /quiet
Yet nothing happened, the program file did not have a folder called Nvidia, the games still says it cannot start since it cannot activate its physics stream....
