No help at this point, but only Win9x used GetLastError from KERNEL32.DLL. On Windows NT/2K/XP/... GetLastError ist only a redirection to RtlGetLastWin32Error in NTDLL.DLL. (to keep compatibility with Win9x programs)

Programs might also use "FindWindow" in different versions to check if they are already running.
