Why (LoadTypeLibEx failed : : Error loading type library/DLL. (Exception from HRESULT

[glitteringsound]

Hello,

I am Loading type library from C++/CLI with following lines of code.

[DllImportAttribute("oleaut32.dll", SetLastError = true, CharSet = CharSet::Unicode, PreserveSig=false)]

static void LoadTypeLibEx( String^ strTypeLibName, RegKind regkind,[MarshalAs(UnmanagedType::Interface)] interior_ptr typeLib );

Object^ oTypeLib;
LoadTypeLibEx( strSubject,RegKind::RegKind_None, &oTypeLib);

It again and again giving me same exception, all I have registered type library with regsrv32, placed in current directory and given full qualified path but still its giving me same exception. Any way around?

Regards
Usman
