LoadLibrary help

Hi,

first, sorry for my english.

I'm a developer that are doing a multiplatform app using C++ and Qt, but I have to use LoadLibrary to open a DLL.

My application has to work in Window 32 or 64 bit and Linux 32 or 64 bit (in Linux is working now)

I'm using this sentence to load it:

HINSTANCE h = LoadLibrary("nsNEVLibrary.dll");

the returned "h" is 268435456 that is not a valid library handle

and GetLastError return 127

nsNEVLibrary.dll is located in C:\Neuroshare\NeuroshareLibraries and this path is in my environment variable path

I run "dependecy walker" to check if I have some missing libraries but no, I have all needed libraries in my C:\windows\system32

Can anybody help me?

Thank you in advance.
