Proved finally. 

A dirty patch in dlls/ole32/storage32.c CreateFileW in lines 6132ff will make
the program work:

  hFile = CreateFileW( pwcsName,
                       accessMode,
                       FILE_SHARE_DELETE | FILE_SHARE_READ | FILE_SHARE_WRITE,
/*                       shareMode, */,
                       NULL,
                       OPEN_EXISTING,
                       FILE_ATTRIBUTE_NORMAL | FILE_FLAG_RANDOM_ACCESS,
                       0);

No more exceptions. Conclusion: The program does 2 times a CreateFileW with
dwSHaredMode = 0 (exclusive) on the same file name. There is no CloseHandle in
between. The second call will fail. 

MSDN states: ... dwShareMode = 0. Prevents OTHER! processes from opening a file
or device if they request delete, read, or write access ... 

Wine may be too restrictive when a single process uses such a buggy file
handling. As I have no Windows machine to check this out, hopefully someone can
build a test case in the native environment and post the results.

Best regards.
