physxdloader.dll missing

[Maasogist]

So yeah i tried alot of ♥♥♥♥ on there but when i click the simple reinstall physx thing in steamapps > metro 2033 it just says ''text'' instead of something installing it and i tried downloading the file and i put it both in metro2033 and system32 and it works for like 2 seconds and then the exe file crashes and my nvidia corporation > physx > common is COMPLETELY EMPTY. so i'm getting pretty annoyed here haha. anyone please help? ( i5, nvidia geforce 315M ) tried finding new physx driver download too but i got a message that its an older version and its aborted. my physx version is 09.13.0725
