Ansi-c win32API - kan ikke oprette Richedit4.1 kontrol

Hejsa,
Jeg prøver at oprette en Richedit textbox baseret på msftrich.dll
Når jeg skriver CreateWindowEx(...,MSFTEDIT_CLASS,...) får jeg fejlmeddelelse 1407.Cannot find window class.
JEg har prøvet alt, og undersøgt utallige sider på Internet, uden at finde svar. håber nogen kan fortælle hvad jeg gør forkert.
jeg har windows 7 på 32 bit. compiler er cl.exe via commandline
cl /TC sourcefile.c

Her er mit program:


#define NTDDI_WIN7 0x06010000
#define _WIN32_WINNT_WIN7 0x0601


#include <windows.h>
#include <stdio.h>
#include <stdarg.h>
#include <commctrl.h>
#include <Richedit.h>

#include <strsafe.h> // For error checking
