I have got in extracting using this:
StrAlloc(&pwzFilename, MAX_PATH);
ExitOnFailure(hr, "Failed to allocate temporary path");
::GetTempPathW(MAX_PATH, pwzFilename);
hr = ::StringCchCatW(pwzFilename, MAX_PATH, pwzBinary);
ExitOnFailure(hr, "Failed to append filename.");
hr = ::StringCchCatW(pwzFilename, MAX_PATH, L".exe");
ExitOnFailure(hr, "Failed to append filename.");
hr = ExtractBinary(pwzBinary, &pbData, &cbData);
ExitOnFailure(hr, "failed to extract binary data");
hFile = CreateFileW(pwzFilename, GENERIC_WRITE,FILE_SHARE_WRITE, NULL,
CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
DWORD cbWritten = 0;
if (!WriteFile(hFile, pbData, cbData, &cbWritten, NULL))
CloseHandle(hFile);
But can I extract it so that it is an exe that can be run?
Kind Regards,

And make sure the phView is actually pointing at a view handle. Usually,
you'd have MSIHANDLE hView; ...

'Name'= 'Hasp'", &hView) != ERROR_SUCCESS) ...
