I am getting a returned exception while trying to use the function FMOD5\_System\_Create().

The exception is a System.BadImageFormatException.

Here is the code I am using to initialize fmod:

public struct Factory  
{  
public static RESULT System\_Create(out System system)  
{  
return FMOD5\_System\_Create(out system.handle);  
}

```
    #region importfunctions
    [DllImport(VERSION.dll)]
    private static extern RESULT FMOD5_System_Create(out IntPtr system);

    #endregion
}

```

If anyone can help me understand what is happening, I would be much appreciated.

It may be that the lib you are trying to use is for the wrong architecture or platform.
