GMK 1.2.4 Installation Error

Hi Friends, GMK I got some errors while installing the 1.2.4 version. I have read the installation guide and there I applied exactly as written ones. Also on my computer installed the latest version of PhysX SDK, and ultimately gives an error like this:


Error 59 fatal error C1083: Cannot open include file: 'NxPhysics.h': No such file or directory c:\torque\torque 3d 2009 beta 5\engine\source\t3d\physics\physx\px.h 31 GMK1 DLL


Pointed part of the error code:

//
// This PhysX implementation for Torque was originally based on
// the "PhysX in TGEA" resource written by Shannon Scarvaci.

Please help me for this problem solving.

Thanks for your attentions.
