IExtractImage error in Windows 2000

[Ed Neary]

When I attempt to extract a thumbnail from a simple JPG in Windows 2000 I get
an error. This works fine in Windows XP and 2003 Server.
The error is 0x80004002 - "No such interface supported".

I have called ::CoInitializeEx(NULL, COINIT_MULTITHREADED); before running
this code.

Below is the code snippet showing the failure

DWORD dwPriority = 0;
DWORD dwFlags = IEIFLAG_SCREEN;
HBITMAP hBmpImage = NULL;
DWORD dwRecClrDepth = 8;
SIZE prgSize;

prgSize.cx = lRes;
prgSize.cy = lRes;

hr = pIExtract->GetLocation(wszPathBuffer, MAX_PATH, &dwPriority,
&prgSize, dwRecClrDepth, &dwFlags);

if(SUCCEEDED(hr))
{
// Failure occurs here... 0x80004002 is returned.
--> hr = pIExtract->Extract(&hBmpImage);

You need to be apartment threaded, not mulitthreaded.
