Are you sure you downloaded the right file?
I right-clicked the 16bit sample from the link and saved
it to my harddrive to test.

is it possible that Cimage class change the "BI_BITFIELDS compressed 16-bit bmp"

It could be the version of CImage you're using however.
What Visual Studio version are you using?

Bitmap::Bitmap(
    IN const WCHAR *filename, 
    IN BOOL useEmbeddedColorManagement
    )
{
    ...
    lastResult = DllExports::GdipCreateBitmapFromFile(filename, &bitmap);
