Cant install Physx 3.3

Folks, sorry for topic,
but i tried at least 3 times before to post it , really i cant install on my machine xp 32 , exe seems corrupted on link:

https://developer.nvidia.com/sites/default/files/akamai/apex/secure/physx/physx_3_3_0/RC3_17045688/PhysX-3.3.0_PC_SDK_Core.exe

All my files are md5:c4a3bff1edaabdff4635e8e07e4c599e
Someone has same problem?

You can try this, the .exe is self extracting…try to see if you can open it with your favorite archive tool…ex. 7-Zip. If you can successfully open the executable you can just extract the contents.

it’s ok in an another machine, perhaps a trivial antivirus lock, I will investigate .
thanks
