           Summary: CapCut installer fails: CreateFileW with
                    FILE_ATTRIBUTE_DIRECTORY | FILE_FLAG_BACKUP_SEMANTICS
                    | FILE_FLAG_POSIX_SEMANTICS  should create a directory
                    instesd of a  file.

I tried the installer from bugreport
https://bugs.winehq.org/show_bug.cgi?id=58635 but it fails instantly with a
error messagebox.

I think I managed to track down the bug:

The installer does:
KERNEL32.CreateFileW(0012f4c4
L"C:\\users\\louis\\AppData\\Local\\\CapCut",00000001,00000003,00000000,00000001,03000010,00000000) 

Then an empty file "CapCut" is present in Appdata\Local\ dir. 

After that it tries to create L"C:\\users\\louis\\AppData\\Local\\CapCut\\User
Data" and L"C:\\users\\louis\\AppData\\Local\\CapCut\\User Data\\Log" in which
Log is a file. This all fails as a file CapCut is already present.

Manual workaround to fool the installer: mkdir
~/.wine/drive_c/users/**/AppData/Local/CapCut before you start the installer,
then it won't crash.

Apparently on windows one can create a directory with CreateFile with the flags
used by the installer; below is a simple test program I tested on windows and
that creates a directory:

#include <windows.h>
#include <stdio.h>
#include <shlwapi.h>

// compile: x86_64-w64-mingw32-gcc a.c -lshlwapi

int main()
{
    char path[] = "c:\\log";

    HANDLE h = CreateFileA(
        path,
        GENERIC_READ | GENERIC_WRITE,
        0,
        NULL,
        CREATE_NEW,
        FILE_ATTRIBUTE_DIRECTORY | FILE_FLAG_BACKUP_SEMANTICS |
FILE_FLAG_POSIX_SEMANTICS ,  // 0x03000010,
        NULL);

    if (h == INVALID_HANDLE_VALUE) {
        DWORD err = GetLastError();
        printf("err %d\n", err);
        return 1;
    }

    printf("%p\n", h);

    BOOL ret = PathIsDirectoryA(path);

    printf("PathIsDirectoryA returned %d\n",ret);

    return 0;
}

Output on windows:

00000000000000c0
PathIsDirectoryA returned 16

Output on wine:
000000000000005c
PathIsDirectoryA returned 0
