Installation Of PhysX

Hi,

Im working for an online game publisher. Currently im working for creating a setup file for one of our games. To let our customers see better experience i would like to ask 2 questions in case someone alraedy had answer :)

1- are there any turkish setup file for physx? i couldnt find at turkish nvidia page (we can do the localization if nvidia stuff would like to build)

2- how can i detect nvidia physx is intalled or not. via registry or somelocation? does it have a policy fo installation of program so i can track and detect?

i hope im asking right place ty for your support :P
