Bug ID: 51881
           Summary: 32bit LoadLibraryEx with
                    LOAD_LIBRARY_AS_DATAFILE_EXCLUSIVE cannot open 64bit
                    DLL
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: loader
          Assignee: wine-bugs@winehq.org
          Reporter: info@daniel-marschall.de
      Distribution: ---
Following code fails on a 32 bit app which tries to edit the resources of a 64
bit DLL (in order to edit its resources):
hmod = LoadLibraryEx(FileName, 0, LOAD_LIBRARY_AS_DATAFILE_EXCLUSIVE)
GetLastError() reports code 193 (ERROR_BAD_EXE_FORMAT)
This behavior is not correct since LOAD_LIBRARY_AS_DATAFILE and
LOAD_LIBRARY_AS_DATAFILE_EXCLUSIVE should only open the file as resource file
and not try to load the image.
Code used here:
